How big is the ridge?

Ridge is a common name in land use, which means that a certain width of mound is divided on the land surface (higher than the original plane). In this way, the mound formed is called ridge and ridge platform, and the ditch formed next to it is called ridge ditch. There is no specific measure of area and size.

Mu is a unit of land area in China, equal to 60 square meters, or about 666.667 square meters.

Fifteen acres equals one hectare. The abbot of 60 square meters was chosen because of the ancient counting method in China, in which counting was mostly carried out in units of ten, while in ancient times, handling was mostly carried out in units of "60".

Unit conversion

1 mu = 10 minute, 1 mu =60 square abbots =6000 square feet; 1 m =3 feet; 1 m2 =9 square feet; 1 square foot = 1/9 square meters, so 1 mu =6000/9 square meters; 1 =600/9 m2 =66.67 m2。

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, how many mu is128m2? The calculation method is 128 plus half of 128: 128+64= 192, and then move the decimal point three places to the left, that is, the mu of 128 square meters is 0. 192.

Mu is square meters, and the calculation formula is "divide by three, move right by three". If you want to calculate how many square meters 24.6 mu is equal to, 24.6÷3=8.2, it will be 16.4 after doubling, and then move the decimal point three places to the right, and the square meter will be 16400.
