Extended data

Mu is the unit of land area in China, which is equal to 60 square meters, or about 666.67 square meters. Fifteen acres equals one hectare. The 60-square abbot was chosen because of the ancient counting method in China. At present, most counts are based on ten, while in ancient times, carry was based on "60". For example, a nail is 60 years.

The square meter is changed to mu, and the formula is "add half to the left and move three". 1 m2 = 0.0015mu, for example, converting 128 into mu means adding 128 to half of 128: 128+64= 192.

Mu is square meters, and the calculation formula is "divide by three, move right by three". If you want to calculate 24.6 mu and convert it into square meters, the calculation method is 24.6÷3=8.2, which is 16.4 after doubling, and then move the decimal point three places to the right, which is 16400.
