History
The are (a) is a metric unit of area introduced in France in 1795, shortly after the creation of the metric system.
It was designed for measuring land and plots, especially in agriculture.
One are was defined as a square with sides of 10 meters, which means:
1 are = 10 m × 10 m = 100 square meters (m²)
Even though it is not an official SI unit today, it is still used in many countries for measuring land areas, often alongside hectares (ha) and square meters (m²).

Common Usage
- Ares (a) are typically used in agriculture and real estate for measuring smaller plots of land.
- Square meters (m²) are used for construction, design, and smaller property areas.
For example, a small garden of 2 ares equals 200 square meters.
Ares to Square Meters Conversion Formula
The conversion is straightforward:
m² = a × 100
Example:
Convert 5 ares to square meters.
5 × 100 = 500 m²
So, 5 ares equal 500 square meters.
Conversion Table
| Ares (a) | Square Meters (m²) |
|---|---|
| 0.5 a | 50 m² |
| 1 a | 100 m² |
| 2 a | 200 m² |
| 3 a | 300 m² |
| 5 a | 500 m² |
| 10 a | 1,000 m² |
| 20 a | 2,000 m² |
| 30 a | 3,000 m² |
| 50 a | 5,000 m² |
| 100 a | 10,000 m² |
Interesting Facts
- The hectare (ha) is equal to 100 ares, or 10,000 m².
- The are was one of the first decimal-based area units when the metric system was introduced.
- In some European countries, small plots of land are still described as “a few ares” rather than in m².
