How many grams of ancient gold bars were there?

In ancient times, gold bars were generally 3 1625g, but they were also said to be156.25,625g.

According to the query of Jintou.com and Baidu Encyclopedia, the weight of a standard gold bar is116.64g (equivalent to 3.746 ounces), and there is no uniform regulation on the weight of gold bars, and gold is not the basic currency in China after the Han Dynasty. Only in some cases does it represent a certain value. Therefore, before the middle of the Qing Dynasty, gold was cast into ingots for circulation. Moreover, in ancient China, gold and silver were in units of two, and sixteen taels were a catty. So there were no gold bars in ancient China. But the ancient Jin has always been considered as 500 grams, and one Jin is equal to 16 Liang. Therefore, based on this, one or two ounces of gold in ancient times is 3 1.25 grams. It is also said that in ancient times, a catty was 600 grams, so one or two was 37.5 grams. Gold bars, bars made of gold, each weigh twelve taels, and some weigh five taels or twenty taels, so through calculation:10 * 31.25 = 312.5, 5 * 31.25 =156.
