History
The square meter (m²) is the base SI unit of area, officially adopted in 1875 when the International Bureau of Weights and Measures was established.
The are (a) predates it slightly and was introduced in 1795 during the creation of the metric system in France.
Since 1 are = 100 m², converting square meters to ares is simple: divide by 100.

Common Usage
- Square meters (m²) are used for houses, rooms, and construction projects.
- Ares (a) are used for larger outdoor plots, such as gardens, yards, and farmland.
For instance, a house with a yard of 800 m² has an area of 8 ares.
Square Meters to Ares Conversion Formula
The formula is:
a = m² ÷ 100
Example:
Convert 2,500 m² to ares.
2,500 ÷ 100 = 25 a
So, 2,500 square meters equal 25 ares.
Conversion Table
| Square Meters (m²) | Ares (a) |

| 50 m² | 0.5 a |
| 100 m² | 1 a |
| 200 m² | 2 a |
| 500 m² | 5 a |
| 1,000 m² | 10 a |
| 2,000 m² | 20 a |
| 3,000 m² | 30 a |
| 5,000 m² | 50 a |
| 7,500 m² | 75 a |
| 10,000 m² | 100 a |
Interesting Facts
