Area units
Edit any field; all others stay in sync. Uses the international statute mile (1609.344 m), yard, foot, and inch (exact SI definitions), the international acre (4840 yd²), and the hectare (10,000 m²).
How this area converter works
Land and floor area units
Area measures surface size in two dimensions. Property listings, maps, agriculture, and DIY flooring all use different traditional units, so the same field can be listed in acres in one country and hectares in another. This converter links common metric and imperial area units so you can compare listings or material estimates quickly.
Typical fields include square kilometres, square miles, square metres, square feet, acres, and hectares. Editing any value recalculates the others from a shared square-metre amount.
Handy reference factors
- 1 hectare = 10,000 m² = 2.47105 acres (approx.)
- 1 acre = 4,046.8564224 m²
- 1 square mile = 2.589988110336 km²
- 1 m² ≈ 10.7639 ft²
Worked example
A city apartment of 85 m² is about 915 ft². A paddock listed as 2 hectares is about 4.94 acres or 20,000 m². A county-scale area of 10 square miles is about 25.9 km².
Choosing a unit
Use square metres and square feet for rooms, flooring, and paint coverage. Use hectares and acres for farms, parks, and large plots. Use square kilometres or square miles for cities, lakes, and map regions. When a listing mixes units, convert everything into one unit before calculating price per area.
Common mistakes
- Confusing hectares with acres — a hectare is larger (about 2.47 acres).
- Multiplying length conversions twice incorrectly when going from m² to ft² (scale by the square of the linear factor).
- Using land area units for volume (m³) problems such as soil or concrete.
FAQs
- Is an acre a fixed shape?
- No. An acre is an amount of area, not a required rectangle size.
- Are survey feet different?
- Some land records historically used US survey feet. This converter uses the international foot / metre relationships common in everyday conversion tools.
