The ratio of gold to grams is 500, so 180÷500=3.6.
Weight units "Jin" and "G" have fixed conversion methods: 1000 g = 1 kg, 1 kg =2 kg, 1000=2 kg, 1 kg =500 g.
There is no "Jin" in the international standard unit, which is a unit in China.
From the perspective of law and life, China's laws clearly stipulate that units such as "Jin" and "kg" can be used as quality units in various occasions, which are legally equivalent and have legal effect.
Excluding traditional Chinese medicine, 1 kg is equal to 500 grams, which is equal to 10. In the measurement of traditional Chinese medicine, 1 kg is equal to 500 grams, which is equal to 16.
From the unified measurement of Qin Shihuang to the early days of the founding of the People's Republic of China, the hexadecimal system of one catty was adopted. On June 25th, 1959, the State Council issued the "Order on Unified Measurement System" to retain the market system;
"The market system was originally set at two per catty 16. Due to the trouble of conversion, it should be changed to twelve taels per catty. " The measurement of traditional Chinese medicine remains unchanged.
According to Hong Kong law, one kilogram is equal to one hundredth of a load or sixteen taels, that is, 604.82 grams (g).
Table system commonly used in Taiwan Province market: 1 kg = 600g. But Jinmen and Mazu are adjacent to Fujian Province, so Taiwan Province Gold is not needed. The so-called "Jin" is 1 Jin = 500 grams.
