How to Convert Ares to Square Meters

The are (a) is an agrarian unit of the International System, intermediate between the square meter and the hectare. By definition, an are corresponds to the area of a square with 10-meter sides, which is exactly 100 square meters. A hectare is therefore equal to 100 ares.

The Conversion Formula

To convert a measurement from ares to square meters, simply multiply the value in ares by 100:

square meters = ares × 100

To convert from square meters to ares, perform the inverse operation, dividing by 100:

ares = square meters ÷ 100

Practical Examples

  • 1 are = 100 m²
  • 5 ares = 5 × 100 = 500 m²
  • 10 ares = 10 × 100 = 1,000 m²
  • 100 ares = 100 × 100 = 10,000 m² (= 1 hectare)

When the Are Is Used

The are is rarely used in everyday language today, but it still appears in Italian cadastral documents, where land areas are often expressed in hectares, ares, and centiares (the 'ha-a-ca' system). Knowing the value of the are in square meters is therefore useful for those who need to interpret a cadastral survey or a land sale deed.
