What Is an Acre?
An acre is a unit of area equal to 43,560 square feet (about 4,047 m²). The word comes from Old English meaning “open field.” The modern legal definition was standardised in the 19th century.
One acre is roughly the size of an American football field without the end zones. As a square, one acre has sides of about 208.7 feet (63.6 m).
How to Calculate Acreage
Formula: A = w × l
Multiply width by length to get the area. To convert to acres, divide square feet by 43,560 (or use the unit selector above).
Example: A rectangular plot measures 300 ft × 150 ft.
- Area in sq ft: 300 × 150 = 45,000 ft²
- Acreage: 45,000 ÷ 43,560 = 1.033 acres
Working in meters: Multiply w (m) × l (m) to get m², then divide by 4,046.86 for acres, or divide by 10,000 for hectares.

Frequently Asked Questions
How many square feet are in an acre?
There are 43,560 square feet in one acre. An American football field (including end zones) covers about 1.32 acres (57,600 sq ft), so one acre is slightly less than a standard football field.
How do I calculate acreage from feet?
Multiply width (ft) × length (ft) to get square feet, then divide by 43,560. For example, a 200 ft × 100 ft plot = 20,000 sq ft ÷ 43,560 = 0.459 acres.
How many acres is a hectare?
One hectare equals 2.471 acres. Hectares are the standard land measurement unit in most metric countries; acres are used primarily in the US and UK.
What is the difference between acreage and square footage?
Both measure area, but they are used at different scales. Square footage is used for buildings and rooms; acreage is used for land parcels. 1 acre = 43,560 sq ft. For large properties it is more practical to say '2.5 acres' than '108,900 sq ft.'
