One acre is a traditional unit of measurement in China, which is usually used to measure the land area. This kind of unit is often used in agriculture, forestry, fishery and other fields, as well as estimating land area in daily life.

Mu is widely used. In agricultural production, farmers usually calculate the planting area according to the number of acres of land, so as to distribute seeds and fertilizers reasonably. In forestry, mu is often used to evaluate the area and growth of forest. In fishery, mu is used to measure the area and production capacity of farms.

In addition to its application in agriculture, forestry and fishery, mu also plays a role in urban planning and construction. For example, when calculating the cost of construction land, factors such as the number of acres of land and geographical location are usually considered.

In addition, in daily life, we will often encounter concepts related to mu, such as the floor space of a house, the area of a garden and so on. By using mu units, we can measure the land area more accurately, so as to better manage and plan resources.
