How Many Grams Of Gold In 1 Ounce Of 22K Gold?

1 Ounce = 31 grams.
But the gold is 22k means you have to multiply .916.
So the 22k Gold = 31* .916 grams pure gold.

Both above answers are incorrect.
For some weird reason there are 31.1 grams by weight to One Ounce of Gold.
I say weird because there are 28 grams of almost everything else to One Ounce.
Troy ounces and Avoirdupois ounces.
Now, the next step is to realise that karats are a measure of Purity.
24K = 100% Au.
22K = 100% x 22 divided by 24 = 28.5 grams of Au for one ounce.

example: You  have a gold coin that is 22k and it weighs an ounce. That does not mean you have an ounce of gold. I know that sounds stupid but you have 2% of metal that is not gold in that ounce contributing to the weight that makes it an ounce cause its is not pure like 24k. So a typical ounce of pure gold is 33.etc grams...so at 22k estimated, you would have about 31.etc grams of gold.
