From: Square Meters (m²)
To: Square Feet (ft²)
Area units measure the size of a two-dimensional surface. Different systems are used worldwide, with square meters (metric) and square feet/acres (imperial) being the most common.
The square meter is the SI derived unit of area. It represents the area of a square with sides of one meter. Square meters are used globally for measuring floor space in buildings, land area for smaller plots, and many other applications.
Floor area, apartment size, small land plots, carpet area, tile coverage
Several derived units are used for areas of different scales:
| Unit | Symbol | Equals |
|---|---|---|
| Square Centimeter | cm² | 0.0001 m² |
| Square Meter | m² | 1 m² |
| Are | a | 100 m² |
| Hectare | ha | 10,000 m² |
| Square Kilometer | km² | 1,000,000 m² |
The hectare (ha) is particularly important for measuring land area in agriculture and forestry, while square kilometers (km²) are used for expressing the area of cities, lakes, and countries.
| Square Inch (in²) | 0.00064516 m² |
| Square Foot (ft²) | 0.09290304 m² |
| Square Yard (yd²) | 0.83612736 m² |
| Acre (ac) | 4,046.8564224 m² |
| Square Mile (mi²) | 2,589,988.110336 m² |
In the United States and some other countries, imperial units are commonly used for measuring property sizes, building dimensions, and land area. The acre is particularly important for rural land measurements, while square feet are standard for residential and commercial floor space.
The acre is one of the most important imperial area units. Historically, an acre was defined as the area that could be plowed in one day with a yoke of oxen.
• Approximately the size of a football field without the end zones
• Equal to 43,560 square feet
• About 40% of a hectare (0.4047 ha)
In the US, the acre is the standard unit for measuring larger residential plots, farms, ranches, and forested areas. It remains essential for property transactions, zoning, and land management.
1 square = 100 square feet
Used in North America for roofing materials. A "square" of shingles covers 100 sq ft of roof area.
1 tsubo ≈ 3.306 m²
Traditional Japanese unit used for measuring building areas and land plots.
1 dunam = 1000 m² (metric dunam)
Used in many Middle Eastern countries including Israel, Turkey, Jordan, and Lebanon.
1 rood = 1,012 m² (approx.)
Historical unit of area in the UK, equal to 1/4 of an acre.
1 township = 36 square miles
Used in US Public Land Survey System for dividing large areas into sections.
1 barn = 10⁻²⁸ m²
Used in nuclear physics to measure cross-sectional area of atomic nuclei.
• 1 m² ≈ 10.764 ft² (multiply by 10.764)
• 1 hectare ≈ 2.471 acres (multiply by 2.471)
• 1 km² ≈ 0.386 mi² (multiply by 0.386)
• 1 ft² ≈ 0.093 m² (multiply by 0.093)
• 1 acre ≈ 0.405 hectares (multiply by 0.405)
• 1 mi² ≈ 2.59 km² (multiply by 2.59)
