About this tool
Convert land and surface area between 11 units: square kilometer, meter, centimeter, millimeter and micrometer; hectare; acre; square mile; square yard; square foot and square inch. It is useful for property listings, garden plans, flooring and maps. Every conversion goes through square meters. The imperial factors (acre, square mile, square yard, square foot, square inch) are exact, so 1 acre is exactly 43,560 ft² and 1 square mile is 640 acres. The menus show full names with symbols such as m² and ha, and the result is labeled with the symbol. Results show up to 8 decimals.

Common problems
- Mixing up linear and square units
- A square kilometer is 1,000,000 square meters, not 1,000. Do not use the length converter for areas.
- Hectare or acre?
- One hectare is 10,000 m² and one acre is about 4,047 m², so a hectare is roughly 2.47 acres.
