Gold Weights and Measures

Determine the value of a gold coin can be difficult.

First, the amount of metal weighs? While the price of gold is usually expressed in dollars per ounce troy oz, the stocks of metric tons of large generally indicated - quite a different scale of measurement. Nor is the weight of the AV system, weigh with people and most of the rest of the United States. So how much is your bracelet in 18 carat goldworth it? Confused?

per troy ounce gold futures to detail is the predominant. Most of the coins is based in Troy ounces and the future standard contract for the supply of 100 Troy. The standard gold bar is given as 350-430 pounds per troy ounce in weight, instead of the appropriate number. even greater amounts of metal are often thousands or even millions of ounces specified - for the determination of the price-based to maintain oz.

The level of smaller amountor 480 grains - is most often used by jewelers, the troy ounce is divided into 20 penny weights. That's all for the troy weights. Grain, pennyweight, and are used routinely ounces, pounds and tons of rare.

weigh less prominently used in the U.S., but there is much to precious metals in any quantity, loved the metric system. Metric weights per gram, which weighs less than a third of a gram is based. 1,000 grams is called a pound and a thousand kilograms (one millionGrams) is equal to one tonne - also known as a ton.

Here are the conversion factors between Troy and metric systems:

Troy CONVERT METRIC

Grains

To convert grams multiplied x.0648

Penny Weights

To convert grams to multiply x 1.555

Oz

To convert to grams, multiply x 31.10

To convert kilogramsmultiplyx 0.031104

To convert to tons by multiplying x 0.000031

To convert to TROY

Grams

To convert to grains multiply x 15.43

To convert multiply pennyweights x.643

To convert to ounces, multiply x.032

Kilogram

To convert to ounces, multiply x 32.15

To convert to Penny WeightsMultiply x 643.015

Tons

To convert to ounces, multiply x 32,150.75

The use of these conversion factors to eliminate possible sources of error that would result from the use of ounces lighter than the AV 35.3 oz await if the bar weighed on a scale of AV could - if you sell a kilo bar will paid based on 32.15 oz

And while there are other methods of weight - DRAM Pharmacists, AV stone imperialOnce, etc. - you can not forget! They are not used for precious metals.

The carat is a very confused customer. Yes, it is a measure of weight - but the weight of precious stones, the weight of the base metal. One carat, in terms of gold, is a measure of purity. And muddy the issue a bit 'more, it is abbreviated as K or KT.

The measure of gold purity

Back to that 18-karat gold bracelet. E '75% of gold, because pure gold is toobe used as a jewelry cloth. jewelry in gold would be easily bent or scratched, alloys are added to harden it.

Strictly speaking, there is no such thing as 100% pure gold. investment-grade gold bars and coins are usually refined to content contain more than 99% gold. And while there are several measures of purity of gold, which describes in the final analysis, each of the percentage of precious metal alloys .

Carat

Even in this caseUnit of weight for gold - a measure of the purity of gold jewelry:

24K Gold 99.9% or higher
22 carat 91.6%
21 carat 87.5%
20 carat 83.3%
18K 75.0%
15 carat 62.5%
14K 58.5%

Fineness

Particle size is expressed in parts per thousand, as well as parts per one hundred percent. Delicacy, purity is the specification standard for gold bars and coins for investment-grade. The London Bullion Market Association predicts that baror 99.9% - for a good supply of at least 999.0 end.

To get the value of your gold, multiply the weight in ounces for the percentage of actual gold content, and then times the price per ounce.

For this volume: 2 ounces (Troy) gold at $ X.75 = $ 2,100 x 1400/ounce real value of gold

That of course does not include sentimental value.
