Units explained
Are
An are is a metric unit of area equal to 100 square meters. It is used in some European countries for land measurement, especially for smaller plots like vineyards and gardens.
Introduced as part of the French metric system in 1795. The name comes from the Latin 'area' meaning surface or open ground.
Ares are still used in some European countries (especially Switzerland and France) for small-plot land measurement. In Switzerland, an are is a common unit for vineyard size. Most modern contexts prefer square meters or hectares.
Defined in 1795 in France as part of the original metric system.
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.
