Area Converter
Convert between square meters, square feet, acres, hectares and more area units instantly.
What is an Area Converter?
An area converter is a tool that helps you convert measurements of two-dimensional space from one unit to another. Area is calculated by multiplying length by width and is expressed in square units.
Area conversion is essential for real estate, construction, agriculture, interior design, and land surveying. Different countries and industries use different units - the metric system (square meters, hectares) is standard internationally, while imperial units (square feet, acres) are common in the US and UK.
Our converter handles all common area units and provides accurate conversions for any size - from small spaces measured in square inches to large land areas in square kilometers.
Area Conversion Formulas
Metric to Imperial
- Square meters to Square feet: sq ft = m² × 10.7639
- Hectares to Acres: acres = ha × 2.47105
- Square kilometers to Square miles: sq mi = km² × 0.386102
Imperial to Metric
- Square feet to Square meters: m² = sq ft × 0.092903
- Acres to Hectares: ha = acres × 0.404686
- Square miles to Square kilometers: km² = sq mi × 2.58999

Frequently Asked Questions
How many square feet are in an acre?
There are exactly 43,560 square feet in one acre. An acre is defined as an area of 1 chain (66 feet) by 1 furlong (660 feet), which equals 43,560 square feet. This is roughly the size of a football field without the end zones.
How do I convert square meters to square feet?
To convert square meters to square feet, multiply the square meter value by 10.7639. For example, a 50 m² room equals 50 × 10.7639 = 538 square feet. Remember that you're converting area, not length, so the conversion factor is the square of the length conversion.
What's the difference between a hectare and an acre?
A hectare is a metric unit equal to 10,000 square meters (about 2.47 acres), while an acre is an imperial unit equal to 43,560 square feet (about 0.405 hectares). Hectares are used internationally, while acres are common in the US and UK for measuring land.
How big is a square kilometer compared to a square mile?
A square kilometer (km²) is about 0.386 square miles. Conversely, a square mile is about 2.59 square kilometers. One square mile equals 640 acres or approximately 259 hectares.
Why do I need to square the conversion factor for area?
Area is a two-dimensional measurement (length × width). When you convert between units, both dimensions change. For example, 1 meter = 3.28 feet, but 1 square meter = 3.28 × 3.28 = 10.76 square feet. This is why the area conversion factor is the square of the length conversion factor.
Area Conversion Tips
- Remember the rule: Area conversion factors are length factors squared
- Quick estimate m² to sq ft: Multiply by 10 for a rough estimate (actual: 10.76)
- Acres to hectares: Divide by 2.5 for a quick estimate (actual: 2.47)
- Football field reference: About 1.32 acres or 5,351 m²
- For real estate: US uses square feet, most other countries use square meters
