Technical notes
Acreage Calculator converts the area you enter into acres (and hectares, square feet and square metres) using fixed area ratios — 1 acre = 43,560 sq ft = 4,046.86 m².

Results are rounded for display; the underlying calculation keeps full precision.
Worked example
A plot measuring 200 ft × 150 ft = 30,000 sq ft ÷ 43,560 = 0.689 acres (1 acre = 43,560 sq ft).
FAQ
Are the acres based on square feet?
Yes. The tool multiplies length by width to get square feet, then divides by 43,560 square feet, which is one acre.
Does the Acreage Calculator send my numbers to a server?
No. The Acreage Calculator runs entirely in your browser, so the values you enter never leave your device.
What units should I enter?
Enter both the length and the width in feet; the result is given in square feet, acres, and hectares.
Does it work for non-rectangular plots?
It assumes a rectangle; for an irregular plot, split it into rectangles and add the areas together.
