Area Converter

Area is a two-dimensional measure of space — it tells you how much surface is covered. Area scales as the square of length, so unit conversions involve squared factors. The SI unit is the square meter (m²), from which all other metric area units derive.

In everyday use, hectares (ha) and acres are most common for land measurement. 1 hectare = 10,000 m² (a square 100m × 100m). 1 acre = 4,046.86 m² ≈ 0.4047 ha. The acre is still widely used in the US, UK, and India for real estate and agriculture.

Square feet (ft²) are dominant in US real estate — apartments and houses are measured in ft². 1 ft² = 0.0929 m², so to convert ft² to m², divide by 10.764. Square kilometers and square miles are used for larger areas like countries, cities, and national parks.

This converter covers all common area units used in real estate, agriculture, construction, cartography, and scientific work, from square millimeters up to square miles.
