* A unit called the po = 6 cheok in the 3rd century and 6th – 7th centuries, but 5 cheok in the 7th – 14th centuries. Thus, the multiples for larger units do not apply.

** The unusual multiplier for the li is due to the influence in 1905 of the Japanese system of lengths. It makes the li 1/10th of the Japanese ri.
