Convert Ar (a)

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.
• Squaremillimeter (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
