Unit | Factor |
---|---|

Square kilometer (km²) | 0,0001 |

Hectare (ha) | 0,01 |

Square meter (m²) | 100 |

## Use of the Ar:

**Land measurements**: Particularly in urban areas or for smaller parcels of land, size is often expressed in acres.**Agriculture**: On smaller agricultural areas or in market gardens, the size of the land or a specific section can be given in ares.**Construction**: When planning buildings or other structures, the size of the underlying land or a specific area may be measured in acres.

## Conversion to other area units:

One acre is equal to 100 square meters. It is therefore relatively easy to convert the ar into other common units of area:

**Square kilometers (km²)**: One ar equals 0.0001 km².**Hectare (ha)**: One hectare is equal to 100 ares.**Square meter (m²)**: One acre equals 100 m².**Square decimeter (dm²)**: One acre equals 10,000 m².**Square centimeter (cm²)**: One acre equals 1,000,000 cm².- Square
**millimeter (mm²)**: One ar equals 100,000,000 mm².

With a direct relationship to the square meter, the conversion between the Ar and other common area units is fairly simple and straightforward
