Formula
Hectares = Ares ÷ 100 | Ares = Hectares × 100
One hectare equals exactly 100 ares. One are equals 100 square meters, and one hectare equals 10,000 square meters. The conversion is a simple factor of 100 in either direction.
Worked Examples
Example 1: Farm Plot Conversion
Problem:A French farmer owns a field listed as 450 ares. Convert this to hectares, acres, and square meters.
Solution:Hectares = 450 / 100 = 4.5 ha Square meters = 450 × 100 = 45,000 m² Acres = 45,000 / 4,046.856 = 11.12 acres
Result:4.5 hectares | 45,000 m² | 11.12 acres
Example 2: Residential Plot
Problem:A property listing in Switzerland shows a plot of 0.08 hectares. Convert to ares and square meters.
Solution:Ares = 0.08 × 100 = 8 ares Square meters = 0.08 × 10,000 = 800 m² Square feet = 800 × 10.764 = 8,611 sq ft
Result:8 ares | 800 m² | 8,611 sq ft
Frequently Asked Questions
What is an are and how does it relate to a hectare?
An are is a metric unit of area equal to 100 square meters. It was originally defined in the French metric system during the 1790s as the primary unit of land measurement. A hectare equals exactly 100 ares, or 10,000 square meters. The word 'hectare' literally combines 'hecto' (meaning 100) with 'are.' While the hectare became the dominant unit for measuring agricultural land and large plots worldwide, the are remains useful for smaller parcels such as residential lots. In many European countries, the are and its derivative, the centiare (1 square meter), are still used in property descriptions and legal land documents.
How do I convert ares to hectares and vice versa?
Converting between ares and hectares is straightforward because they share a clean decimal relationship. To convert ares to hectares, divide the number of ares by 100. For example, 250 ares equals 2.5 hectares. To convert hectares to ares, multiply the number of hectares by 100. So 3.75 hectares equals 375 ares. This simple factor-of-100 relationship exists because the metric system was designed around powers of ten. You can also think of it in terms of square meters: multiply ares by 100 to get square meters, or multiply hectares by 10,000 to get square meters, then convert between the two using the appropriate factor.
Where are ares commonly used as a unit of measurement?
Ares are most commonly used in European countries for measuring small to medium-sized land areas, particularly in real estate and agriculture. In France, Belgium, Switzerland, and Luxembourg, property listings and land registries frequently express areas in ares and centiares. Germany, the Netherlands, and several Eastern European nations also use ares for cadastral surveys and land transactions. Japan uses a similar unit called the 'a' that is equivalent to the are. In contrast, English-speaking countries like the United States and the United Kingdom predominantly use acres and square feet. International scientific contexts tend to prefer hectares or square kilometers for larger areas.
How do ares and hectares compare to acres and square feet?
One are equals 100 square meters, which is approximately 1,076.39 square feet or about 0.02471 acres. One hectare equals 10,000 square meters, roughly 2.471 acres, or about 107,639 square feet. To put this in perspective, an American football field (including end zones) is approximately 0.535 hectares or 53.5 ares. A standard tennis court is about 2.6 ares. An acre, the common imperial land unit, is approximately 40.47 ares or 0.4047 hectares. These conversions are essential when dealing with international real estate or agricultural data, as different countries use different land area measurement systems.
Why was the are created and how did it become part of the metric system?
The are was created during the French Revolution as part of the comprehensive metric reform of 1795. The French National Assembly sought to replace the chaotic patchwork of feudal land measurement units — which varied from region to region — with a rational, decimal-based system. The are was defined as 100 square meters, making it easy to scale up (hectare = 100 ares) or down (centiare = 0.01 are = 1 square meter). Although the International System of Units (SI) does not officially include the are, the hectare is accepted for use with SI. The are filled an important niche for everyday land transactions where square meters were too small and hectares too large.
