A **surface** is measured in the following units:

1 square kilometer (km^{2}) corresponds to 100 hectares or a square with a side length of 1 km.

1 hectare (ha) corresponds to 100 ares; 1 Ar (a). One ar is equal to 100 square meters.

1 square meter (m^{2}) corresponds to 100 dm^{2} or a square with a side length of 1 m.

1 square decimeter (dm^{2}) corresponds to 100 square centimeters.

1 square centimeter (cm^{2}) corresponds to 100 square millimeters.

1 square millimeter (mm^{2}).

Square millimeters | mm² | 1 | mm² | = | 0.000001 m² |

Square centimeters | cm² | 1 | cm² | = | 0.0001 m² |

Square decimeters | dm² | 1 | dm² | = | 0.01 m² |

square meters | m² | 1 | m² | = | 0.01 a |

Ar | a | 1 | a | = | 100 m² |

Hectares | Ha | 1 | Ha | = | 10,000 m² |

Square kilometre | km² | 1 | km² | = | 1,000,000 m² |
