To allow users to enter values in different units of measurement, this page specifies several custom unit for this datatype:

 * corresponds to::0.000001 km², km2, sq.km, sqkm, square kilometer, square kilometers, square kilometre, square kilometres

The main unit is m², i.e. values without a unit are interpreted in this way.

Editors can add more units and alternative representations. To allow users to enter units in several forms, you add alternate representations separated by commas; for example this datatype supports "squared" using  2  or a Unicode character.

The main unit is the first unit with 1:1 correspondence; for this datatype it is m². In the factbox and inline queries, values display converted into this unit first (unless a property specifies different display units).
