1 2 oz to grams. What is an ounce and how is ounce converted to grams? Convert oz to grams

When buying or selling precious metals, an unfamiliar unit of measurement is often encountered - an ounce. It is much simpler and more understandable, we are accustomed to using the metric system in everyday life, to measure weight in grams. However, in international practice, this is the standard for determining the value of precious metals. The answer to the question: 1 ounce, how many grams, is not as simple as it might seem at first glance.

Translation problems

Translation problems arise due to the presence of different names depending on the field of use and the country where it is used. The confusion is also added by the fact that some states, for example the USA, still do not use the metric system, preferring the traditional one.

Averdupua (oz or oz at) - 28.35 g, used by the United States as a measure of weight.
Fluid ounce (fl oz) - 29.573 531 ml, used to determine the volume of liquid.
Troy ounce (toz or ozt) - 31.1034768 g, all over the world this value is used to measure the weight of precious metals.

Troy ounce

Troy ounce is a common measure for precious metals.

Simplified meaning for translation: 1 ozt - 31.1035 grams.

It should be noted that in international trade this unit is used only to determine the mass of pure metals of the highest standard.

In world currency markets, the XAU index is used to indicate the rate of 999.9 gold. Mints of different countries minted coins weighing 31.1 g. Many, both old and modern money made of gold and silver, have this denomination.

origin of name

Uncia - Latin term means 1/12 part. This concept came to us from Ancient Rome, but the troy ounce appeared as a measure of weight much later. This name has nothing to do with ancient Troy and comes from the name of a French city Troyes (Troyes), Champagne province.

In the Middle Ages, famous champagne fairs were held here, which brought together traders from different countries. The presence of various measures has led to the need to apply some unifying quantity.

The troy pound became such a unit and its 1/12 part is the troy ounce. In the 19th century, Great Britain became the center of world trade. Which inherited and finally consolidated the application of this measure, as the main one in the international trade in precious metals.

Using recalculation in practice

The need to translate ounce-gram arises, in most cases, when trying to calculate, or silver per gram in national currency, for example in rubles, today. The calculation algorithm is quite complicated and requires knowledge of not only the cost of the metal in dollars per ounce, but also the currency quotes of rubles / dollar. It looks like this:

the cost of gold (dollars / ozt) divided by 31.1035 and multiplied by the dollar / rub rate, we get the gold price in rubles / year.

There is a calculator for calculating the value of gold, which calculates according to the data of the Central Bank, which greatly simplifies and speeds up obtaining the desired result.

On the Internet, you can find a large number of unit converters, when using such programs for converting the weight of precious metals, it is important to remember that you need a troy ounce, and not any other value.

The metric system of measures is familiar to a modern person. But novice buyers of investment bullion may be surprised that a special unit of measurement is used as a standard for the weight of precious metals - a troy ounce (troy ounce, t oz or oz t), which has nothing to do with the SI or the system of measures used in USA. Faced with the precious metals market for the first time, it is important to understand why and how much a troy ounce of gold weighs in grams.

Weighing as a comparison of the weights of two objects has been familiar to mankind for thousands of years. Lever scales are present in images from the earliest civilizations. This instrument was used almost unchanged until the twentieth century.

In medieval times, even money was determined by weighing. As a standard, jewelers and traders in Europe used grains of wheat and barley, and in the east they preferred carob seeds. Due to the stability of their weight - four such seeds made up one carat.

A medieval silver penny weighed one pennyweight and was divided into two halves at halfpenny and four farthing by weight. The pennyweight was 1/240 troy pounds, which in turn was equal to 5670 grains of barley, selected in a special way (with the same mass and length) so that they could be used as units of measurement.

The Troy measuring system is believed to have originated in the 15th century in the French city of Troyes in Champagne, where major trade fairs were held. The king of England of French origin, Henry II, adjusted the British coinage system towards unification with the weighing methods in Troyes. By 1527, this system had become the official benchmark for gold and silver in Britain. The United States followed suit in 1828.

Ozt in our time

Before the adoption of the metric system, troy units were used in various parts of Europe. Their values \u200b\u200bvaried by several percent.

The modern unit of weight corresponds to the imperial troy ounce and the following proportions are adopted for it:

12 ozt is 1 tr. lb;
1 ozt contains 20 pence.

Similar ratios have a connection with the British monetary system based on the old pound 240p. Therefore, such a weighing system is called a coinage. In the modern world, the coin weight is used only for weighing precious metals and stones. According to ISO4217 codes, the following designations are assigned to the weight units of investment metals:

XAU - t oz of gold;
XAG - t oz of silver;
XPT - t oz of platinum.

Today ozt is the international standard for precious metals trading. All major trading platforms expose prices without comment, how many grams are in a troy ounce of gold and what quality, since experienced investors are in any case aware of such nuances.

SI and everdup equivalent

The Troyes measure of scales involves dividing the pound into 12 parts. This is very different from the everyday weighting system used in the United States, in which 16 ounces is one pound.

The traditional American measurement of weight is called the everdupois system. The standard pound is about 21.5 percent heavier than the troy pound and in terms of grain size was 7000 grains (grains) versus 5760 (12 × 480) in the troy. Gran is the smallest unit of mass for the Pharmacy, Troy and Everdupois systems.

To understand how much an ounce of gold is in grams, you need to decide on the net and gross standards for measuring precious metals. On the precious metals exchanges, one ounce of gold always means a troy ounce of gold with a purity of 99.99%. This is the maximum purity of the noble metal; complete removal of impurities is technically impossible. The same applies for 1oz of silver or other precious metal.

Troy weight refers to pure metal only, any other components are subtracted from the net weight. 31.1034768 grams - this number with an accuracy of the seventh decimal place is enough for any practical application of knowing how many grams are in an ounce. 31.103 is an easy-to-remember figure that means how much an ounce of gold weighs in grams in an approximation convenient for use in everyday life.

A large number of unit ratios can be made between metric, troy, and everdup systems due to the cumbersomeness of traditional measures. For understanding, the following values \u200b\u200bwill be sufficient, given to kilograms in SI:

1kg \u003d 35.2740 oz;
1kg \u003d 32.1507 ozt;
1oz \u003d 0.9114 ozt;
1oz \u003d 0.02835 kg.

For weight measurement, a troy grain can be used, which is equivalent to a mass of 0.0648 grams.

Weights and coins can be roughly divided into two categories. The first is historical or everyday coins made of noble metal. The second includes those intended for investment purposes along with ingots.

Such coins are minted in accordance with the troy weight system and the following values \u200b\u200bare traditional for them:

1/10 t oz;
¼ t oz;
½ t oz;
1 t oz.

Minted at the South African Mint. In 1980, it accounted for 90% of all world gold coins. The name itself is a combination of the person's name on the obverse and the unit of the South African currency. In the 1870s. and the 1980s. Some countries banned the import of Krugerrand during the years due to links with South African apartheid. Now the coin is popular with collectors and investors.

The production levels of the Kruger Rand have varied considerably over half a century. In the early years, 40 thousand coins were minted, in 1970 the issue increased to 200 thousand copies and continued to grow. In total, about six million Krugerrands were produced.

The coin was developed as a vehicle for private investment in gold, sold at the equivalent of its price and had no par value, but had legal tender status. In addition to the one-ounce Krugerrand, small coins were minted in half, quarter and tenth oz t. The emission contains about 46 million oz t of gold (about 1500 tons). The Krugerrand's success sparked a reaction in other state mints, which also began to mint fractional ounce coins.

Maple Leaf

Manufactured by the Royal Canadian Mint since 1979. Face value - 50 Canadian dollars. The market value varies depending on. Its purity sometimes reaches 99.999%.

In addition to standard denominations, it is produced in weights of 1/25 and 1/20 t oz. The obverse and reverse represent the profile of Elizabeth II and a Canadian maple leaf. In 2007, the Royal Canadian Mint introduced a coin with a face value of $ 1 million with a gold price of $ 2 million.Its diameter was 50 cm, a thickness of 3 cm and a weight of 100 kg.

A series of coin bars issued by the People's Republic of China. An official of the Chinese Mint introduced the panda gold coin in 1982. Since then, its design has changed every year.

This coin comes in various sizes and variations ranging in weight from 1/20 t oz to 1 t oz. There are also a number of silver coins with the same characteristics. There are 5 and 12 t oz "giant panda" coins.

Manufactured since 1986 in 1/10, ¼, ½ and 1 t oz. The specified weight of gold is guaranteed by the US government. The silver content of the alloy is 3%, which makes the coin not like the Krugerrand.

The 22 carat gold alloy (916 carat) is the traditional English gold. It has not been used in US coins since 1834. By 1837, the gold content of the coin alloy had dropped to 90%. By the time the American eagle appeared, the content had again increased to 91.67%.

The Perth Mint is minted by a company wholly owned by the Australian government. Denominations of 1/20, 1/10, ¼, ½, 1, 2, 10 oz and 1 kg of 99.99% gold were produced. They are legal tender in Australia. The annual limited edition with original design makes the Australian nugget attractive to collectors.

It has two unique features: a two-tone effect due to rough matte and glossy surfaces and an individually rigid encapsulation that protects the coin from bumps and scratches. These features were unusual for standard gold coins and allowed the nugget to carve a unique niche in the market.

Austrian Philharmonic (Philharmonic)

The coin has been minted from 99.99% pure gold since 1989. Issued annually in four denominations, sizes and weights. Legally as a means of payment on the territory of Austria, after circulation inevitably settles in private collections. According to the World Gold Council, it was the world's best-selling coin in 1932, 1995 and 1996. It is produced in a weight of 1 t oz and a face value of 100 euros.

On the reverse side there is a set of musical instruments representing the Vienna Philharmonic, on the reverse - a large organ of the concert hall. The denomination of the philharmonic is indicated in shillings (up to 2002) or euros. Weight, alloy purity and year of manufacture are also indicated. Since 2008, not only gold, but also silver philharmonics have been minted. Their design is identical to the gold coin except for the stated par value of 1.5 euros.

It is obvious that the minting of bullion coins not only has not died, but is also experiencing a rebirth. Investors all over the world buy and sell gold in troy ounces, so the idea of \u200b\u200bacquiring legal tender in multiples of ozt will always be attractive.

One of the earliest problems with language adaptation for the fisherman was the need for me to start thinking in ounces, not in the usual grams. After all, here almost all the sinkers and jig heads, as well as rod tests by the weight of the used lures, are marked in ounces. The line is marked in pounds.

The main weight measures you need to know are OZ (english ounce; fr. once; reduction - OZ) and LB (english pound,; fr. livre; reduction - LB).

Ounce (lat. uncia) - the name of several units of weight, as well as measures of the volume of liquid, one unit of measure of force, and even several monetary units. The word originally meant one twelfth something whole.

The term originates from ancient Rome, but was also widely used as one of the main weight units of medieval Europe. Today it is used in the precious metals trade and in several countries where weight is traditionally measured in pounds (for example, the USA, Canada and the UK).

It should be noted that at different times and in different places, some pounds and ounces were different from others, i.e. they "weighed" in different ways. But I will focus only on those that we are currently using directly.

And for this you need to get acquainted with the weight system, which is called everdupois or averdupois, which is based on lb. (lat. pondus - weight, weight)consisting of sixteen ounces.

Word avoirdupois comes from a French and Middle English expression avoir de pois literally meaning "Loose goods" or "Goods sold by weight"... Initially, this term was used to refer to goods that were weighed on large steelyards or scales during sale, and only then they began to call the system of units of weight used to sell such goods.

Here are some basic numbers to remember

1 pound averdupua (LB or lb) = 0.45359237 kg, i.e. 0.454 kg or 454 grams.

1 ounce averdupua (OZ or oz at) = 28.3495231 grams or just 28.35 grams.

For simple mathematical actions in your head, it is enough to remember that:

1 pound equals 450 grams, and 1 ounce is 28 grams.

What markings can be found in local stores

Rod test- the maximum weight of the load that is recommended to be used with this rod. It is usually measured in ounces, i.e. there is marking in OZ... For instance, 1/2 - 1 OZ, means that the rod is ideal for fishing with lure weights from 14 to 28 grams.

The line is labeled according to its tensile strength in pounds, i.e. in LB... For example, a fishing line marked 10 LBmeans that its tensile strength is 4.54 kg.

Reels are usually provided with two markings - the length of the line in accordance with its diameter, or the diameter of the line with its breaking strength. For example, you can wind 100 meters of line with a diameter of 0.1 mm on a reel, or 100 meters of line 10 LB.

Also, when talking to local fishermen, you will hear that they show off their catches in pounds (pounds) too. For example, "I caught 60 pounds of sturgeon", ie the fish weighed 27 kg. But you must admit that 60 is more than 27 ...

A small table of common symbols

1/8 oz \u003d 3.5 grams

3/16 oz \u003d 5.3 grams

1/4 oz \u003d 7 grams

3/8 oz \u003d 10.6 grams

1/2 oz \u003d 14 grams

1 oz \u003d 28.35 grams

1 1/4 oz \u003d 35.35 grams

1 1/2 oz \u003d 42.35 grams

2 oz \u003d 56.7 grams

3 oz \u003d 85 grams

4 oz \u003d 113.4 grams

5 oz \u003d 141.75 grams

I have used these ounce-to-grams conversions when shopping for jig heads, small arched or center hole olives (sinkers for through rigging), and large weights for bottom fishing.

Often, the labeling on packages is doubled - both in ounces / lbs and in grams / kilograms. If this is not the case, then you can easily convert ounces to grams, and pounds to kilograms yourself. After a year, using the local weight system, you will normally understand it and when buying gear, you will think not in grams, but in ounces.

Very often there is such a problem as the need to convert ounces to ml: we are talking about fluid ounces. Why might it be necessary to convert one value to another, and what are they? Is such a unit in use now and where did it come from?

A fluid ounce is a unit of volume commonly used to measure liquids. It is approximately equivalent to 30 milliliters. Throughout history, many definitions of this unit of measurement have been used, but in the modern world only two remain in common use, in England and in the United States.

Volume matching

In the UK, a fluid ounce is 1/20 pint, or 1/160 gallon. If you translate such an ounce into milliliters, then it will be 28.4. An ounce of fluid in the United States is 1/16 of a pint and 1/128 of a gallon. There are many different ounces, most of which are units of mass, but the fluid ounce is different. Sometimes the specification of which ounce is meant is omitted, and it is often possible to find the name simply "ounce" in relation to any of these quantities. What we are talking about usually becomes clear from the context.

Story

Initially, a fluid ounce was called the volume that one weight ounce of a substance occupies. In England, ounces were used to measure the volume of wine, and in Scotland, water. Therefore, the volume of all ounces was different, depending on the density of the liquid. The situation was further complicated by the practice of allowances, when in the Middle Ages the unit of measurement was not always equal to the sum of its parts.

In 1824, the British Parliament defined a gallon as the volume of 10 pounds of water. The gallon was divided into four quarts, the quart into two pints, the pint into four gills, and the jill into five ounces. Thus, 1 gallon became equal to 160 ounces. And for an ounce was taken the volume of liquid, which was occupied by 1 ounce of avourdupua. Now these ratios are in force, except that 1 gallon was revised to be equal to 4.54609 liters, and accordingly 1 fluid ounce of the British Empire became equal to 28.4130625 milliliters.

In the United States, the ounce was also based on the gallon, which in turn is derived from the wine gallon. The wine gallon was 231 cubic inches and existed in England until 1824. When the international inch was adopted, the US fluid ounce changed accordingly and became equal to 29.5735295625 milliliters, which is approximately 4% more than the United Kingdom fluid ounce volume.

Fluid ounce

The oz is used abroad as a short designation for the ounce. You can meet her if you make purchases, for example, at online auctions. Any liquid goods will be measured in ounces: eau de toilette, perfume, aromatic oils, rare liquid spices and more. Naturally, we are talking about buying goods from America and Great Britain, as well as countries that are part of the Commonwealth of Nations, such as Australia and Canada. It is worth noting that when buying goods from the United States, a simplified measure is used, an ounce in this case will be equal to 30 milliliters.

Converting ounces to milliliters can also be useful when trying to use recipes for various dishes. If you come across a cookbook from the UK or Australia, then you know how to convert ounces to milliliters, for example, 10 ounces will contain 300 milliliters. Sometimes, the ounce and its fractions are indicated on measuring cups for liquids. Very often you can find such a designation of a measure of volume on baby dishes, for example, feeding bottles. A standard 100 ml serving will correspond to just over three ounces. This is possible, because such a product is produced mainly for the whole world, but milliliters can also be seen on them at the same time.

Thus, there should be no problem with determining the number of milliliters per fluid ounce. The main thing to remember is that there are several varieties of them, which can play a significant role when buying expensive goods. Interestingly, the US has already introduced the metric system at the legislative level, but the Americans are so used to the existing one that it has not yet taken root.

Greetings to my readers! In France, there is the city of Troyes, famous for architectural monuments of the Middle Ages, giblet sausage and low alcohol drinks.

Trois is the historical capital of the Champagne province, which gave the name to the sparkling wines that the whole world drinks. And the city itself also gave the name, only not to wine, but to the unit of measurement of the mass of precious metals. Troy ounce of gold in grams equals 31.1034768 and is still used in jewelry, banking and cosmetology.

Since ancient times, it has been customary to measure the mass of a material in pounds, and these pounds were not identical. The Russian pound was equal to 0.41 kg, and the pound sterling (silver coins) was about 0.35 kg. According to one version, it was he who later turned into the British pound - a currency that is more expensive today than the dollar or the euro.

Ancient Rome also had its own pound - libra (327.45 g). The twelfth part was called an ounce.

Briefly about the history of the origin of the troy ounce

The first mention of the troy ounce (denoted as ozt or t oz) is attributed by historians to 1390. But the fair in Troyes (Champagne) has been known in Europe since the 12th century, and probably appeared around V. So (in fractions of a pound) grain, cosmetics, medicines were calculated.

The words "Troyes" and "Troyes" sound different for the Russian ear, but it is worth looking at the French spelling of the city's name - Troyes - and the similarity becomes obvious.

Ounces types

In addition to mass, in Rome they measured in ounces:

area: 1 oz - 2400 roman sq. feet, that is, 29.9 m²;
length: 1 oz - 1/12 Roman foot - 0.0246 m;
capacity (volume): 1 oz - 1/12 sextaria - 0.0372 cups.

As a measure of mass, an ounce existed in many countries of Europe and beyond and was equal to a different number of metric grams. The discrepancies have survived to this day.

Ounce can mean not only t oz, but also other varieties:

fl oz - fluid ounce (there are English and American, both are about 30 ml);
oz at - ounce of averdupua, derived from the trading pound (one oz at - about 28 g).

How many grams are in one ounce of gold

Troy, aka gold coin, a pound weighed 373.2417 g (the same as 87.5).

Troy ounce (1/12 lb) equals 31.1034768 g - this cumbersome number is often reduced to 31.1035, which one cannot but rejoice in trying to remember it.

One kilogram contains 32.1507 ozt of gold.

Online converter

Translating values \u200b\u200binto decimal is mentally difficult. For our convenience, there are online calculators and converters that allow you to enter indicators in different units of measurement and get the result without long calculations. Here is one of them:

Measure in different countries

Until the 20th century, which greatly unified the units of measurement of mass, length and other parameters, residents of different countries used their own measures, different from those preferred by their neighbors. This complicated trade even then, and a modern man will become all the more confused in diversity. If you come across an ounce in fiction or historical literature, it could be:

1/8 deutsche mark (Germany until the end of the 19th century);
1/12 pound (Italy);
1/16 of the trading pound (Portugal and Spain);
1 doubloon (South America)
3 ducat coin (Sicily);
1 liang, aka tael (China).

How much is 1 ounce of gold worth

The cost of a 999 gold unit for 81 years (1919–2015, except for the war and post-war years) was determined by the London fixing, established on the London Interbank Stock Exchange. In 2015, the assessment system underwent changes - now electronic auctions are held. twice (at 10:30 and 15:00 GMT).

Until 2015, the price of gold was determined by 5 companies - the main traders and producers of gold bars in the world. Currently, 13 banks from different countries are participating in the auction, including Canada, South Africa, China, Switzerland, USA and France. In Russia, there are no organizations accredited to participate in interbank trading.

Since the rate changes every day, fluctuations are best.

Gold | RUB | 1 oz

Gold | USD | 1 oz

Conclusion

I hope you understand more clearly why the price of an ounce of gold is 31.1034768 times higher than the price of a gram and why it is called "troy"! Stay with me and share new information with your friends. See you!
