- The basic unit of measure for the area is the square meter (m
^{2}) or derived units created by adding SI prefixes, eg. one square kilometer (km^{2}) or one square centimeter (cm^{2}).

- 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 (mi
^{2}), square feet or square inch.
