Metric area units
Square meters (m²) are the SI unit. Hectares (10,000 m²) are standard for land, and square kilometers (1,000,000 m²) for regions and countries. Smaller surfaces use square centimeters or square millimeters.

About area conversion
Area measures the size of a two-dimensional surface — a room floor, a plot of land, a country. Different fields use different units, so converting between them quickly is essential for property, construction, science and travel.
Imperial & US area units
Square feet and square yards are common in real estate and construction in the US and UK. Acres (43,560 ft²) measure land, and square miles measure large regions. One square mile contains 640 acres.
Acres vs hectares
Acres and hectares are both land units. One hectare equals about 2.4711 acres, and one acre equals about 0.4047 hectares. Hectares dominate internationally; acres remain standard in the US, UK and parts of South Asia.
How the math works
Each unit is stored as its size in square meters. Conversion is a single multiplication and division: value × from-factor ÷ to-factor. Everything runs locally in your browser at full double-precision.
Frequently asked questions
- How do I convert square meters to square feet?
- Multiply the square meter value by 10.7639. For example, 50 m² equals about 538.196 ft². The factor is the square of the meter-to-feet conversion (3.28084²).
- How big is one acre?
- One acre equals 4,046.8564224 square meters, or 43,560 square feet. It's roughly 90% of an American football field, or about 0.405 hectares.
- What is a hectare?
- A hectare is 10,000 square meters — a square 100 m on each side. It is the most common unit for measuring land area in agriculture and forestry worldwide.
- Why are area conversions different from length conversions?
- Area is two-dimensional, so the conversion factor is squared. If 1 ft = 0.3048 m, then 1 ft² = 0.3048² ≈ 0.0929 m². This converter handles that for you automatically.
