How it works
Area units arise in architecture (square feet, square metres), agriculture (acres, hectares), land registration (roods, perches), and large-scale geography (square kilometres, square miles). The Area Converter handles all major area units and explains the relationships between them.
**Core unit relationships** - 1 square metre = 10.7639 square feet - 1 acre = 4046.86 m² = 43,560 sq ft (a rectangle 66 ft × 660 ft — the old chain × furlong measurement from surveying) - 1 hectare = 10,000 m² = 2.47105 acres - 1 square kilometre = 100 hectares = 247.105 acres - 1 square mile = 640 acres = 2.58999 km²
**Why acres and hectares exist** The acre was historically the amount of land tillable in one day by one ox — standardised in England by Edward I. Its oddly specific size (43,560 sq ft) reflects its origin in the chain-furlong measurement system (a chain = 66 ft, a furlong = 660 ft). The hectare was introduced by the French after metrication as a round-number agrarian unit (100 m × 100 m), matching approximate agricultural plot sizes.
**Architecture and real estate** Square footage vs. square metres is the key conversion for international property listings. A 100 m² flat is approximately 1076 sq ft. Note that "gross floor area" (GFA) and "net floor area" (NFA) definitions vary by jurisdiction — this converter works with whatever area figures you supply.
**Survey units** The rood (¼ acre) and perch/pole (1/160 acre = 25.2929 m²) appear in older property deeds in the UK and Ireland. The converter supports these for historical land records.

Frequently Asked Questions
- 1 acre = 43,560 square feet = 4,046.86 m². The acre originated as the amount of land a yoke of oxen could plough in a day — standardised as a strip 1 chain (66 ft) wide by 1 furlong (660 ft) long. The product 66 × 660 = 43,560 sq ft. It remains the standard land area unit in the US and is still used informally in the UK alongside hectares.
- A hectare is exactly 10,000 m² = 100m × 100m — a clean metric unit introduced after the French Revolution. An acre = 4,046.86 m². So 1 hectare ≈ 2.471 acres. In agriculture, EU and UK land subsidies are calculated per hectare; US farmland is typically measured in acres. Converting between them requires the factor 2.471.
- Square footage (area) and footage (length) are different dimensions. A room measuring 15 feet × 12 feet has an area of 180 square feet — you multiply the two linear dimensions to get area. You cannot convert 'footage' to 'square footage' without knowing both dimensions. Estate agents quote room areas in square feet (US) or square metres (UK) to compare differently shaped rooms.
- A square metre is a square with 100 cm on each side. A standard single bed is approximately 0.9 m × 1.9 m = 1.71 m². A parking space is roughly 2.5 m × 5.0 m = 12.5 m². A tennis court is 260.76 m². A football pitch is 7,140 m² (105 m × 68 m). A hectare (10,000 m²) is slightly smaller than 2 football pitches side by side.
