To convert hectares to acres, multiply by 2.47105. One hectare is 10,000 m², and one acre is 4,046.856 m², so 1 ha = 10,000 ÷ 4,046.856 = 2.47105 acres:
One hectare = 100 × 100 metres = 10,000 m². One acre ≈ 4,047 m² (about 63 × 64 metres).

To convert hectares to acres, multiply by 2.47105. One hectare equals 10,000 square metres (a 100 m × 100 m square). One acre equals approximately 4,046.856 m², so the conversion is 10,000 ÷ 4,046.856 = 2.47105. For example, 5 hectares = 5 × 2.47105 = 12.355 acres. A 100-hectare farm equals 247.1 acres.
To go the other way (acres to hectares), multiply by 0.404686. For example, 10 acres = 10 × 0.404686 = 4.047 hectares. One square kilometre equals 100 hectares = 247.1 acres.
Hectares are the metric standard for land area, widely used in Europe, Australia, and most of the world for agriculture, forestry, and urban planning. Acres are the common unit in the United States and the UK for property, farmland, and planning. You'll need this conversion when reading international agricultural data, buying or comparing farmland across countries, interpreting national park or forest sizes, and working with real estate listings in mixed-unit regions.
One hectare equals 2.47105 acres. This comes from the fact that 1 ha = 10,000 m² and 1 acre = 4,046.856 m², so 10,000 ÷ 4,046.856 = 2.47105 acres per hectare.
One acre equals approximately 0.404686 hectares. To convert acres to hectares, multiply by 0.404686. For example, 5 acres = 5 × 0.404686 = 2.023 hectares.
One hectare is a 100 m × 100 m square — about the size of an international rugby pitch (100 m × 68 m, plus surrounding area). It is 10,000 m² or 107,639 sq ft. In farming terms, 1 ha is a moderately small field.
A standard FIFA football pitch (105 m × 68 m) has an area of 7,140 m² = 0.714 hectares = 1.764 acres. A full hectare is slightly larger than a football pitch.
