The basic unit of measurement of the area in the metric system of measurements is the square meter [m²].
In metrological measurements, as well as in automation, also the derived units used:
- 1 Kilometer² [km²] = 1,000,000 m².
- 1 Hectare [ha] = 10 000 m² = 100 a = 0.01 km².
- 1 Ar [a] = 100 m² = 0.01 ha.
- 1 Meter² [m²] = 100 square decimeters (dm²).
- 1 Decimeter² [dm²] = 100 cm².
- 1 Centimeter² [cm²] = 100 mm².
- 1 Millimeter² [mm²] = 0.01 cm².
