There are 43,560 square feet in one acre so take the length times the width in feet and divide by that figure to find the number or fraction of an acre. If the property is irregular, take length times width of each roughly rectangular chunk and add them together before dividing.
How do you convert an acre measurement to feet? Dimensions of quarter-acre lots vary. Square footage is calculated by multiplying the lot length by its width to arrive at the square footage. If the resulting number equals 10, 912.5 square feet, it is truly a quarter-acre lot. Quarter-acre lots inevitably vary in dimension (length times width), but any combination of calculated dimensions count toward the total square footage.
