1 mu = 60 square abbot = 2000/3m2 = 666.7m2.

1 mu = 100 square meter

1 ha = 10000 m2 = 100 mu = 15 mu.

First, the traditional formula for calculating the number of acres of land:

1 mu = 60 square abbot = 6,000 square feet = 666.67 square meters.

One square meter is equal to 0.00 15 mu.

Simple calculation method, formula ①:

Length (m) x width (m) x 0.00 15 = number of acres.

Example 1: What is the land area of 200m long and 150m wide?

200m x150m x 0.005438+05

=30000Ⅹ0.00 15

= 45 (management unit)

Simple calculation method, formula ②: length (m) width (m) ÷667.

One square meter is equal to 0.00 15 mu.

Exodus 2: What is the area of a piece of land 60 meters long and 40 meters wide?

60m x 40m m ÷667

=2400÷667

= 3.5982 (management unit)

= 3.6 (management unit)

Calculation method of folk formula:

The calculation formula for converting square meters into acres is:

"Add half and move three to the left"

Example 3: 128 square meters, how many acres is it?

Calculation method: First use half of 128+ 128.

128+ 128÷2

= 192

= 0. 192 (management unit)

Then move the decimal point three places to the left, and the mu number is: 0. 192 mu.
