**Acres to square feet** conversion factors are listed below (for both international and survey acres). To find out how many square feet in an acre, multiply by the conversion factors or instead, use the converter if the conversion is between international acres and sq. foot. **If scroll down**, you may also create and print your own custom conversion table create your table.

**1 Acre = 43 560 Square Feet** [For both within international or survey]

**1 Acre = 43 559.825579 Square Feet [survey]**

**1 Acre = 0.999995995 Acre [survey]**

For example, to find out how many sq. feet there are in a half (1/2) acre of land, multiply the acre value by the conversion factor, (1/2) * 43560 = 21780 sq. feet.
