Units explained
Square Dekameter
A square dekameter is a metric unit of area equal to 100 m². It is identical in value to the are.
Derived by squaring the dekameter (10 m). The deca- prefix comes from the Greek 'deka' (ten).
Square dekameters are functionally equivalent to ares. In contexts where the prefix system is preferred, dam² may be used in place of 'are' for clarity.
Dekameter has been part of the metric system since 1795.
Square Hectometer
A square hectometer is a metric unit of area equal to 10,000 m². It is identical in value to the hectare.
Derived by squaring the hectometer (100 m). The hecto- prefix comes from the Greek 'hekaton' (hundred).
Functionally equivalent to hectares. In contexts where the prefix system is preferred over the special name 'hectare', hm² may be used.
Hectometer has been part of the metric system since 1795.
