Square meters to acres converter
This converter turns square meters to acres in one step: 1 acre is 4,046.86 m², so 5,000 square meters are 1.2355 acres. It also converts hectares, square feet, square yards, square miles, are and tsubo – the result appears instantly.
Example: Value 5,000 · from: Square meter (m²) · to: Hectare (ha) → Result: 5,000 m² = 0.5 ha. Source: BIPM – SI Brochure, Table 8: hectare = 10⁴ m², non-SI unit accepted for use with the SI. Updated: .
How it is calculated
Square meters to acres: the formula
Acres = square meters ÷ 4,046.856, or roughly square meters × 0.000247105. In the other direction, square meters = acres × 4,046.856.
- 1,000 m² = 0.2471 acres
- 5,000 m² = 1.2355 acres
- 10,000 m² (1 hectare) = 2.4711 acres
Acre, hectare and square foot
One acre is defined as 4,840 square yards, and the yard is exactly 0.9144 m – that gives 4,046.8564224 m², or 43,560 square feet. A hectare is 10,000 m², so 1 hectare = 2.471 acres and 1 acre = 0.4047 hectares. One square meter equals 10.764 square feet, and 640 acres make one square mile (2.59 km²).
Are, decare and tsubo
An are is 100 m² and a hectare is 100 are. The decare (1,000 m²) is common in Turkey (dönüm) and parts of the Middle East, the tsubo (about 3.306 m²) in Japan.
Honest limits
Regional land units such as the morgen, bigha or rai are left out on purpose – their size differs by country and era. For property boundaries the official land register or survey always overrides a converted value.
