Q: How many square feet are in an acre?

There are 43,560 square feet in one acre. An acre is a unit of land area used primarily in the US, UK, and other countries using the imperial system.

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
