Conversion formula
The conversion couldn’t be simpler:
- Kilograms = Jin × 0.5
- Jin = Kilograms × 2
This 2:1 ratio makes mental math easy. Forgot the exact formula? Just remember: two jin make one kilogram.
Example calculations
- Converting 10 jin to kg
10 jin × 0.5 = 5 kg

Historical background
The jin’s history stretches back over 2000 years. Originally based on weight measurements from the Zhou Dynasty (1046–256 BCE), it was standardized during the Qin unification of China in 221 BCE. The modern 500-gram definition was established in 1959 to align with metric standards.
Kilograms have a shorter but no less fascinating history. Born from the French Revolution’s measurement reforms, the kilogram became the cornerstone of the metric system in 1795. Fun fact: until 2019, it was defined by a physical platinum-iridium cylinder stored in Paris.
Interesting facts
