About the Area Converter
Area measurements vary widely across industries and countries. Real estate often uses square feet or square metres, agriculture favours acres and hectares, while science and engineering rely on SI units. Our area converter bridges all these systems with instant, accurate conversions across 10 common units.
How it works
Every area unit is defined relative to the square metre (m²) — the SI derived unit of area. Your input is first converted to square metres, then every other unit is derived from that base. One acre equals 4,046.8564224 m², and one hectare is exactly 10,000 m². All calculations run entirely in your browser.
Common conversions
One square foot equals approximately 0.0929 m². One acre is about 43,560 square feet. One square mile equals 640 acres or approximately 2.59 km². Whether you are measuring a room, a plot of land, or a city, this converter gives you instant results in every unit.
