Converting weight between metals.
The same piece weighs differently in different metals. Multiply the weight you have by the factor for the metal you want, and you have the weight you will need.
How to use it
Multiply, do not add
Find the metal you are converting from down the left side of the chart, then read across to the metal you are converting to along the top. Multiply your weight by the figure where they meet.
Worked example
5g of platinum, in 9ct gold
5g multiplied by 0.53 equals 2.65 grams
