are to square meter (a to m²) – How to convert a to m²
The are to square meter conversion is one of the most straightforward in the metric system. The are was once widely used across Europe for land measurement, while the square meter remains the universal building block of all metric area calculations. With Jetcalculator, you can convert between them instantly, but let’s first break down what each unit represents.
What is an Are?
An are (a) is a metric unit of land area. It is defined as exactly 100 square meters. You can picture it as a square that measures 10 meters on each side. The are was created during the French Revolution as part of the push for a clear, logical, and universal system of measurement. While it has faded in common usage, you will still find it in older land records and in some rural property descriptions across Europe.
What is a Square Meter?
The square meter (m²) is the foundation of the metric system for measuring area.
-
It is the area of a square that is 1 meter on each side.
-
Every other area unit in the metric system—including the are and hectare—is built from square meters.
-
The square meter is used globally for everything from floor plans and construction projects to agriculture and environmental data.
Conversion Formula: Are to Square Meter
This conversion is as simple as it gets:
1 a = 100 m²
Example:15 a × 100 = 1,500 m²
This straightforward relationship makes the conversion instant and error-free.
For land-specific tasks, the dedicated area converter is especially useful, giving fast and reliable results for real estate, farming, or academic projects.

Did you know?
-
The metric system was introduced in 1795 during the metric reforms of revolutionary France.
-
Although the are has fallen out of favor, the hectare (equal to 100 ares) is still the international standard in agriculture.
-
The square meter is the most widely used unit of area in the world—applied in construction, architecture, science, and everyday life.
-
In many European property deeds from the 19th and 20th centuries, small plots were described in ares, while larger tracts were converted to hectares.
The French Revolution and the Birth of the Are
In 1795, France introduced the metric system as part of its sweeping social and political reforms. The are was established as a practical way to measure plots of land, offering a neat value of 100 square meters. It simplified taxation, property ownership, and trade in a country where dozens of local systems had once confused.
As agriculture expanded, however, the area was considered too small for large estates and farmland. This led to the introduction of the hectare, equal to 100 ares or 10,000 square meters. The hectare soon took over as the main unit for large-scale land use, while the are gradually fading into the background.
This transition shows how measurement systems evolve to meet practical needs: the are laid the foundation, but the square meter and hectare became the units that survived into modern times.

From Simple Squares to Global Standards
The are to square meter (a to m²) conversion may be mathematically simple, but it carries deep historical significance. It represents the move from fragmented local measurements to a universal, logical system that the world still uses today.
With Jetcalculator, you don’t need to worry about remembering formulas. Whether you’re working with historical property deeds in ares or modern floor plans in square meters, you can convert a to m² instantly and accurately. This keeps the link between history and modern practice alive, ensuring clarity and precision in every calculation.
With the Conversion Tools, you can quickly switch between are and square meter, along with dozens of other units.
