In short
One mu is 666.667 square metre, so to convert mu to square metre you multiply by 666.667, and to go back you multiply square metre by 0.0015. 2 mu is 1333.33 square metre, 5 is 3333.33 and 10 is 6666.67. A mu is exactly one fifteenth of a hectare — 666.67 m2 — so 15 mu is a hectare and 6 mu is a little under an acre. The tidy relationship is with the hectare rather than the acre, which is why Chinese agricultural statistics convert to hectares cleanly and to acres awkwardly. The mu is used in mainland China and Taiwan, where farm and rural land is universally measured in mu.
How to use the Mu to Square metre
- Type the value you want to convert.
- Pick the unit you are converting from and the unit you want.
