    About Area Units

    Area measures the size of a surface. It is used in property listings, room planning, flooring, agriculture, mapping, construction and land management.

    Common area units

    • Square meter (m²): standard metric unit for rooms, homes and land plots.
    • Square foot (ft²): common in property and building measurements in the US and UK.
    • Acre: widely used for larger plots of land.
    • Hectare: metric land unit often used in farming, forestry and planning.

    Quick reference

    • 1 m² = 10.7639 ft²
    • 1 hectare = 10,000 m²
    • 1 acre = 43,560 ft²
    • 1 km² = 100 hectares

    Area and volume are closely related, but they are not the same. If depth or height matters, use the Volume Converter instead.

    What is area?

    Area is the amount of surface covered by a shape or space. A square with sides of 1 meter has an area of 1 square meter. A square with sides of 1 foot has an area of 1 square foot.

    Unlike length, area is always measured in square units, such as m², ft², cm² or acres.

    Common metric area units

    • Square millimeter (mm²): used for very small surfaces.
    • Square centimeter (cm²): useful for small objects and surfaces.
    • Square meter (m²): common for rooms, buildings and land plots.
    • Hectare (ha): often used for farmland and large sites.
    • Square kilometer (km²): used for very large areas such as regions or lakes.

    Common imperial area units

    • Square inch (in²): for small surfaces.
    • Square foot (ft²): common in homes, offices and property listings.
    • Square yard (yd²): used for gardens, carpets and outdoor spaces.
    • Acre: popular for land measurement.
    • Square mile (mi²): used for very large geographical areas.

    Area vs volume

    Area describes a flat surface. Volume describes space with depth. For example, a room floor may be measured in square meters, while a water tank is measured in liters or cubic meters.

    If a calculation involves thickness, height or depth, go to the Volume Converter. If it involves side lengths only, try the Length Converter.

    Frequently asked questions
