Acreage Calculator

By Stephen Bucaro

Few lots are exact squares or rectangles. This calculator will tell you the size of an odd shaped lot in acres (or hectares), as long as it has four sides. Enter the length of each side in feet (or meters) in the respective Units boxes. When you click the Calculate button, it will return the square area in the same units. Also, depending upon which radio button you set, it will return the acres (which requires feet) or hectares (which requires meters).

This calculator uses Brahmagupta's Formula, A = SqRt[(s-a)(s-b)(s-c)(s-d)] where a, b, c and d are the lengths of the four sides of the quadrilateral, and s = (a + b + c + d)/2. You can learn more about Brahmagupta's Formula here. Before using this calculator, read My Web Site User Agreement.
