How the Unit Converter works

One gram is 0.0321507466 troy ounces, the reciprocal of the exact 31.1034768 grams in a troy ounce. Both units are fixed by definition, through the grain of exactly 64.79891 milligrams.

Worked through: 20 g x 0.0321507466 = 0.643015 oz t.

Going the other way, one troy ounce is 31.1034768 grams.

For mental arithmetic: Divide by 31.1, or divide by 30 and take off 3.5%.

Scrap gold and jewelry are weighed in grams and paid for per troy ounce, so this conversion sits between the scale and the price. Divide the gram weight by 31.1035, then multiply by the purity: 14k gold is 14/24 gold, 58.3%, so a 10 g 14k chain holds 10 ÷ 31.1035 × 0.583 = 0.188 troy ounces of fine gold. Small gold bars are sold in grams for the same reason: 1, 5, 10, 20, 50 and 100 g are standard sizes, and a 100 g bar is 3.215 oz t.

Precision is worth matching to the input. A measurement given as 1 g carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
