One ounce of gold is equivalent to 31.103 grams of Chinese mass, which is mostly used abroad.
If it’s not gold, though it’s an ounce, it doesn’t necessarily weigh 31.103 grams.
An ounce is about one or two of our country’s old weight and measures (16 two is a catty).
In the old days, the gold received by the bank according to the old system was converted into 1 liang (the old system) equal to 1.005 ounces.
In other words, the old one is a little more than an ounce.
After the implementation of the new system of weights and measures, one ounce will be equal to 31.104 grams, which is equal to 0.622 liang of the local jin system.
