土地亩数怎么算

To calculate the area of land in acres, you can use the following formula:

1 acre = 43,560 square feet

So, to convert the area of land from square feet to acres, you can use the formula:

acres = square feet / 43,560

For example, if you have a piece of land that is 87,120 square feet, you can calculate the number of acres as follows:

acres = 87,120 / 43,560
acres = 2

Therefore, the land is 2 acres in size.
