Some facts

  • The basic unit of measure for the area is the square meter (m2) or derived units created by adding SI prefixes, eg. one square kilometer (km2) or one square centimeter (cm2).
  • It is still common to use some non-SI units in some areas of daily life. For example land area is still measured in ares (a) or hectares (ha).
  • In Anglo-Saxon countries, it is common to use units based on traditional imperial length units like miles or inches. In this way, we get new area units such as square mile (mi2), square feet or square inch.

How to convert

  • Enter the number to field "value" - enter the NUMBER only, no other words, symbols or unit names. You can use dot (.) or comma (,) to enter fractions.
    Examples:
    • 1000000
    • 123,23
    • 999.99999
  • Find and select your starting unit in field "unit". Some unit calculators have huge number of different units to select from - it's just how complicated our world is...
  • And... you got the result in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you're looking for.
