How it works

Formula
Base Unit: 1 square meter (m²)

Metric to m²:           1 mm² = 0.000001 m²  |  1 cm² = 0.0001 m²  |  1 km² = 1,000,000 m²
                        1 hectare = 10,000 m²

Imperial to m²:         1 in² = 0.00645 m²  |  1 ft² = 0.0929 m²  |  1 yd² = 0.8361 m²
                        1 mi² = 2,589,988 m²  |  1 acre = 4,047 m²

Common References:
  1 hectare = 10,000 m² = 2.471 acres = 107,639 ft²
  1 acre = 4,047 m² = 43,560 ft² = 0.405 hectares
  1 sq mile = 640 acres = 2.59 km² = 259 hectares
  Football pitch ≈ 7,140 m²  |  Tennis court ≈ 261 m²

Property (SA/UK/AU):
  500 m² = 5,382 sq ft  |  1000 m² = 10,764 sq ft
  Small holding ≈ 8,500 m² (≈ 2 acres)

Enter an area in any unit and see the conversion to all others instantly. Supports metric (square millimetres to square kilometres), imperial (square inches to square miles), and land-based units (hectares, acres). Includes common property sizes for South Africa, UK, and AU, so you can understand erven, holdings, and land parcels in both systems.

Why this matters

Area (land) is measured differently across the world. Property in South Africa is measured in square metres or hectares; the US uses acres and square feet; the UK uses hectares but also acres. When you're buying property, comparing land sizes, or reading property descriptions, you need to convert between systems. A South African erf of 1000 m² might sound different than 10,764 square feet—but they're the same. This calculator makes those conversions instant and clear.
