The ancient system of weights and measures has undergone many changes. After the Ming Dynasty, it was generally stable with little change, basically around 595g per catty. Until 1929, the measurement reform was carried out, and the old system was changed from 595g to 500g. Thus, from the Ming Dynasty to 1979, the correct formula for converting money into grams should be 595÷ 16÷ 10, and 1 money is about 3.72 grams.

In the early days of the People's Republic of China, one catty was equal to 16 liang, and one liang was equal to ten yuan. "Money" is converted into "gram", and the commonly used conversion method is 500g( 1 kg) ÷ 16 (old system 16 is one kg) ÷ 10 (old system 10 is one kg).

Extended data:

1On June 25th, 959, the State Council issued the Order on Unified Measurement System, which determined the metric system as the basic unit of measurement in China, promoted it throughout the country, and retained the municipal system. "The municipal system was originally set at two per catty 16, but it should be changed to two per catty 12 due to difficulties in conversion." The measurement of traditional Chinese medicine remains unchanged.

From 1979 65438+ 10/month, the unit of measurement in traditional Chinese medicine was also changed to metric system, and "grams, milligrams, liters and milliliters" were used instead of "two, money and minutes".
