"Mu" is a unit of land area made in China, and one mu is equal to 60 abbots. Fifteen acres equals one hectare. If you want to convert it into metric system, an acre is about 667 square meters. But it should be emphasized that this statement is now customized. The word "mu" in the history of China is actually a very vague concept.

Extended data:

How big is an acre of land?

The area of a square with a side length of 100 meter is one hectare.

And one hectare = 15 mu. So one mu =( 100 m) 2 ≈ 666.67 square meters.

1 ha = 15 mu

1 mu =666.67 square meters.

It is about 20 meters long and 30 meters wide, or 10 meters long and 60 meters wide, as long as it grows into a building with a width of more than 600.

One square meter is equal to 0.00 15 mu, and one mu of land is about 666 (countless) 7 square meters.
