The world's gold prices often see are based on ounces as the pricing unit, and 1 ounce = 31.103481 grams. Due to the different calculation methods, the conversion of pounds and grams has also been different in different dynasties. During the Qin and Western Han Dynasty, a pound was equivalent to 258.24 grams, and one or two equal to 16.14 grams. Wang Mang, Eastern Han Dynasty, Wei, Jin, and Northern and Southern Dynasties, a pound was equivalent to 222.73 grams, and one or two equal to 13.92 grams. The early years of the Sui Dynasty, a pound was equivalent to 668.19 grams, and one or two was equal to 41.76 grams. One pound at the end of the Sui Dynasty was equivalent to 222.73 grams, and one or two was equal to 13.92 grams. In the Tang Dynasty, a pound was equivalent to 596.82 grams, and one or two equal to 37.30 grams. In historical materials and existing ancient objects: gold ingots are divided into one, two, two, and even twenty -two, twenty -two, twenty -two, and twenty -two; Two or three hundred and two.

1: Put the gold in the accurate electronic balance first, and then write down the weight. 2: Prepare a cup, put the cup into 90%of the water, put it on the electronic balance, and then peel the zero 3: Kill the gold with silk threads and settle it. Slowly put it in the water until flooding. Note that you must not sink the bottom or hit the wall. At this time, remember the weight displayed on the balance and write it down. 4: The original weight of the gold is divided by the weight in the water and then divided by 19.34 (the density of gold) is equal to the color of this gold
