picul

The picul , shi (), dan or tam, is a traditional Asian unit of weight, defined as "as much as a man can carry on a shoulder-pole". Throughout most of Chinese history, it was defined as equivalent to 120 catties. Some later definitions (British Hong Kong, Chinese market-use system) define it as 100 catties. It is most commonly used in southern China and Maritime Southeast Asia.

==History== The unit originated in China during the Qin dynasty (221–206 BC), where it was known as the shi (石 "stone"). During the Han dynasty, one stone was equal to 120 catties. Government officials were paid in grain, counted in stones, with top ranked ministers being paid 2000 stones.
