Weights & Equivalent

Gold conversion tables

The gold weight conversion procedures of the London Bullion Market Association (LBMA) are used for trading on the London bullion market and accepted internationally. 

Metric-imperial conversions 

The LBMA records its basis for converting the weight of gold bars from grams (metric) to ounces troy (imperial), and vice versa, as follows: 

1 gram = 0.0321 ounces troy 

5 gram = 0.1608 ounces troy

10 gram = 0.3215 ounces troy

20 gram = 0.6430 ounces troy

½ ounce troy = 15.5517 grams

1 ounce troy = 31.1034 grams 

1 kilogram = 32.1507 ounces troy 

1 tonne = 32,150.70 ounces troy
