SponsoredThis converter turns ares into hectares (are to hectare). Enter a value and the result updates as you type. 1 are equals exactly 0.01 hectares.
The are is a metric unit of 100 square meters, a square 10 meters on each side, and the hectare is one hundred ares. The hecto in hectare means one hundred, so ares divide by 100 to give hectares. Land registers in several countries still record small plots in ares, while farms and forests are given in hectares.
The result is rounded to 4 decimal places, but the factor behind it never is, so long chains of conversions stay accurate. You can type decimals, thousands separators or fractions such as 2 1/2, and the conversion table below lists common values.

To convert ares to hectares, divide by 100. For example, 250 ares equals exactly 2.5 hectares.

Hectares and Ares Together
Land records often write an area in both units, such as 2 ha 50 a. To make one number, convert the ares and add: 50 ares is 0.5 hectare, so 2 ha 50 a adds up to 2.5 hectares, or 250 ares. In square meters it is 25,000 m².
NIST SP 811 lists the hectare, 10,000 square meters, among the units accepted for use with the SI, and notes that in 1978 the CIPM allowed the are to continue in use alongside SI units. An are is 1% of a hectare, which the Percentage Calculator can confirm, and a plot measured by its sides can be worked out with the Square Footage Calculator for Gardening and Lawn.
