Karat Gold Conversions
Karat is a measurement of the purity of gold in an alloy. Each karat represents a ratio of 1/24 purity, indicating how many parts out of 24 are pure. Therefore, 24 karat gold is pure, while 18 karat gold is ¾ gold and ¼ alloy (Dictionary of international trade: handbook of the global trade community by Edward G. Hinkelman). Below are some example common used in bullion: -

Gold Weights and Measures
By tradition gold is quoted and traded in troy ounces, these having been adopted by the U.S. Mint for the regulation of coinage in 1828. Unlike 'normal' pounds and ounces there are 12 troy ounces to the troy pound rather than 16. But a troy pound weighs less than in imperial pound (0.82 British/US pounds).
Cutting through all that nonsense a troy ounce is approximately 0.031kg or 31 grams.
The following gives an approximate conversion between traditional and metric weights.
