There are 43,560 square feet in a acre; this is 4,840 square yards. You can find a conversion calculator at http://www.unitconversion.org/area/acres-to-square-foots-conversion.html Originally, the size of an acre was approximately the amount of land an ox could plow in a day. Now, I donât know about you, but that approximation means virtually nothing to me.
43,560 square feet = 1 acre. The math is straight-forward for converting square feet to acres â just divide your propertyâs square footage area measurement by 43,560. The result is the land area in acres. For example, if you have a 17,200 sf lot and need to know the acreage: 17,200 sf / 43,560 = .39 acres. As noted above, our conversion tool is focused on helping you convert square feet to acres (and not acres to square feet) because we use Acres as the primary unit of measurement for the area or size of lots and land on LotNetwork.com.
