How much is a catty?

One Jin equals one Jin (5g), and one kilogram equals two Jin (1g).

Jin is an ancient weight in China, and now it is called Jin for short. Generally speaking, "several catties of meat" and "several catties of cotton" are still common weight units in China's general market. There is a city load above the city weight, in hundredths; There are two, two, ten cents, ten cents, ten cents, ten cents, ten cents, etc. in decimal.

From unified measurement, the first emperor of Qin Dynasty, to the early days of the founding of the People's Republic of China, 16 systems per catty was adopted. On June 25th, 1959, the State Council issued the Order on Unified Measurement System, which kept the market system. "The market system was originally set at 16 taels per catty, but it should be changed to 12 taels per catty because of the difficulty in conversion." The measurement of traditional Chinese medicine remains unchanged.
