To convert hectares to acres, multiply by 2.47105. So 1 hectare = 2.47105 acres. Conversely, 1 acre = 0.404686 hectares. A hectare is a metric unit equal to 10,000 square meters (a square of 100m × 100m). It's widely used in agriculture, forestry, and land planning worldwide. For quick mental math: 1 hectare is approximately 2.5 acres, or roughly the size of 2 international rugby fields.
