斤 jīn — catty; (PRC) weight equal to 500 g

A way to remember it

An axe with the blade at the top left. It is the tool in 断 (to cut through) and 新 (a fresh cut), and on its own it became the weight a load of it made: half a kilo.

A picture that makes the shape stick — not a claim about the character’s history.
