Most popular area conversions

The most searched area conversions are acres to hectares, square feet to square meters, and acres to square kilometers. One acre equals about 0.405 hectares, while a hectare is roughly 2.47 acres — the two main units for measuring land worldwide. For smaller areas, square feet to square meters (1 ft² = 0.0929 m²) is the go-to conversion in construction and real estate.

Understanding area units

Area is measured in square units, scaling as the square of length. The metric system uses square meters, hectares (10,000 m²), and square kilometers, while the imperial and US customary systems use square feet, square yards, acres, and square miles. Land is most often measured in acres (US, UK) or hectares (most of the world), making acre-hectare conversion one of the most common real-world needs.

Quick reference

1 acre = 0.4047 hectares · 1 hectare = 2.471 acres · 1 acre = 4,047 m² · 1 acre = 0.00405 km² · 1 square foot = 0.0929 m² · 1 square meter = 10.764 square feet · 1 square mile = 640 acres. Use the converter for any exact value.

Frequently asked questions

How big is an acre in real terms?

About 4,047 m² — roughly 60% of a football (soccer) pitch, or a square of about 64 × 64 meters. It was historically the area a team of oxen could plow in a day.

What is the difference between an acre and a hectare?

A hectare is metric: exactly 10,000 m², equal to about 2.47 acres. Farmland worldwide is usually measured in hectares; the US and UK still use acres.

Why do area conversion factors look so different from length ones?

Because area scales as the square of length. Since 1 ft = 0.3048 m, one square foot is 0.3048² = 0.0929 m² — the factor gets squared too.
