Evolutionary history

The unified measurement was formulated by Qin Shihuang. Since the founding of New China, China has been using the measurement method of 16 liang per catty. In the Southern Song Dynasty, Yang Hui wrote a poem "20% off the price of a catty": "Seek one thing, every six or twenty-five; Second, ask for abdication125; Three requests, 1875? " It means that one or two equals 0.0625 Jin, and two or two equals 0. 125 Jin?

At that time, the 16-Liang scale was called the 16-Liang scale, which consisted of the Big Dipper, the Southern Dou Six Stars and the Fu Lushou Three Stars. It warns businessmen to be honest and trustworthy and not to deceive others. Otherwise, it is not a blessing to lose one or two, and you will lose your life if you lose two or two.

Because of 1959, one catty is equal to twelve ounces.

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".
