## Units

### Gram (g)

A metric unit of mass equal to one thousandth of a kilogram. Widely used in cooking, nutrition labeling, and science.

### Troy Ounce (oz t)

A troy ounce is a unit of mass used for precious metals such as gold, silver, and platinum. It equals exactly 31.1034768 grams, about 10% heavier than the common avoirdupois ounce.

## Background

A 10-gram gold chain contains about 0.3215 troy ounces of gold. To calculate its melt value, multiply 0.3215 by the current gold price per troy ounce and the purity (karat) percentage. Jewelers in metric countries weigh items in grams, but the reference price is always per troy ounce, making this conversion a daily necessity in the trade.

## Good to Know

The standard 'Good Delivery' gold bar held by central banks weighs about 400 troy ounces (12.44 kg). Investment-grade gold bars for retail buyers come in sizes from 1 gram to 1 kilogram, but the price per troy ounce is always the reference.

## FAQ

### How do I convert grams to troy ounces?

Divide the number of grams by 31.1035. For example, 100 grams ÷ 31.1035 = 3.215 troy ounces. This tells you how many troy ounces of metal you have.

### How much is 1 gram of gold worth?

Divide the current gold price per troy ounce by 31.1035 to get the price per gram. If gold is $2,000/oz, then 1 gram is worth about $64.30. Multiply by the purity fraction (e.g., 18K = 75%) for alloy gold.

### What is the difference between grams and troy ounces for gold?

Grams are a metric unit used worldwide for weighing. Troy ounces are the traditional precious metals trading unit. Gold prices on exchanges are quoted per troy ounce, but physical gold is often weighed in grams, especially in Europe and Asia.

## Non-Frequently Asked Questions

### Why do jewelers not use regular ounces?

Troy ounces (31.1 g) are heavier than regular ounces (28.35 g). The troy system predates the avoirdupois system and was specifically designed for precious metals. Jewelers use troy because it is the historical standard AND because charging by a heavier ounce means higher per-ounce prices.
