To convert square feet to acres, first you need to know how many square feet there are in an acre.
By definition 1 acre is equal to 43560 square feet.
This relationship between square feet and acres can help you convert any area that is in square feet to acres.
Example #1
Convert 87120 square feet to acres.
We can solve this problem by setting up a proportion.
If 43560 square feet is equal 1 acre
87120 square feet is equal to x acres
Here is table that summarizes this problem.
43560 | 1 acre |
87120 | x |
The proportion is 43560 / 87120 = 1 acre / x
After cross multiplication, we get 43560 × x = 87120 × 1 acre
43560x = 87120 acres
x = 87120 acres / 43560
x = 2 acres
87120 square feet is equal to 2 acres.
Example #2
Convert 21780 square feet to acres.
Again, this problem can be solved by setting up a proportion.
If 43560 square feet is equal 1 acre
21780 square feet is equal to x acres
Here is table that summarizes this problem.
43560 | 1 acre |
21780 | x |
The proportion is 43560 / 21780 = 1 acre / x
After cross multiplication, we get 43560 × x = 21780 × 1 acre
43560x = 21780 acres
x = 21780 acres / 43560
x = 0.5 acres
21780 square feet is equal to 0.5 acres.
