Mu is a unit of land area made in China, and one mu is equal to 60 square abbots.

The abbot of 60 square meters was chosen because of the ancient counting method in China. Now, most of the counting is carried in units of ten, while in ancient times, the carrying was carried in units of 60, for example, one nail is 60 years.

Square meter is a metric unit of area, defined as the area of a square with a side length of 1 meter. In life, square meter is usually referred to as square meter or square, and it is called square meter in Hong Kong and Taiwan. Well-field system takes a hundred steps to make an acre (one step wide and one hundred steps long).

Shang Yang's reform in Qin dynasty abandoned the mine field, taking 240 steps as an acre. Qin merged with the six countries, Han inherited the Qin system, and the size of mu was parallel. By the time Emperor Wu of the Han Dynasty unified the number of steps per mu, all the steps were 240 mu, which was implemented throughout the country. Since then, an acre is 240 paces wide, and it has not changed until the end of the Qing Dynasty.

Points are commonly used units of area in rural areas, such as one acre divided into three points, etc. The smaller unit is Li, one acre equals ten points, and one point equals ten points. One acre of land is equal to 666.67 square meters, one acre is equal to 66.667 square meters, and one centimeter is equal to 6.6667 square meters.

Calculation skills of mu and square meter;

1, square meters to mu: the formula for calculating square meters to mu is "add half to the left and move three", for example, 128 square meters is equal to how many mu? The calculation method is to use 128 plus half of 128, that is, 128+64= 192, and then move the decimal point to the left by three places, that is, the mu of 128 square meters is 0. 192.

2. Converting mu into square meters: The formula for calculating mu into square meters is "Divide by three times and move right by three". If you want to calculate how many square meters is 24.6 mu? The calculation method is 24.6÷3=8.2, which is doubled to 16.4, and then the decimal point is moved to the right by 3 places, so the square meter is 16400.

Note: There are three units of land area in China, namely square kilometers (km2), hectares (hm2) and square meters (m2). The use of mu and mu (a) should be avoided, and the symbol of hectare is hm2. ha is not recommended in China.
