Calculate acreage from length and width, known square footage, hectares, square meters, square yards, or square miles. Use this acreage calculator for property lots, farm fields, parcels, pasture, wooded land, gardens, lawns, land value estimates, usable acreage, and acreage conversions.
Length × width:
The calculator multiplies length by width to find square feet, then divides by 43,560 to calculate acres.
Triangle acreage:
Enter base and height to calculate triangle area, then convert the result to acres.
Circle acreage:
Enter a circle diameter to estimate acreage from a round parcel or circular field.
Known area conversion:
Enter square feet, acres, square yards, square meters, hectares, or square miles to convert into acreage and other land units.
An acreage calculator helps estimate land size, usable acres, property value, rent value, and common land area conversions.
It can be useful for buying land, checking lot size, planning farm fields, estimating pasture acreage, measuring wooded property, calculating food plots, and comparing land values.
Your result shows total acres, usable acres, square feet, square yards, square meters, hectares, square miles, estimated land value, annual rent value, estimated taxes, and unused or setback acreage.
Calculate square feet first, then divide by 43,560. For a rectangular parcel, multiply length by width, then divide by 43,560.
One acre equals 43,560 square feet.
One square mile equals 640 acres.
Split the land into smaller rectangles, triangles, or circles, calculate each section, then add the acreage together. For legal property size, use a survey or official record.
