What is an Are?
The are (symbol: a) is a unit of area equal to 100 square meters (10m × 10m). It was defined by older forms of the metric system but is now outside the International System of Units (SI), though it is still accepted for use with SI units. The are is commonly used in cadastral surveying and agriculture, especially in some European countries.
Although not an SI unit, the are is accepted for use with SI units and is particularly useful for measuring land area. Our are conversion tool helps you easily convert between ares and other units. For example, 1 are equals 100 square meters or approximately 119.6 square yards.
What is the SI Status of Are?
The are is not an SI unit, but it is accepted for use with SI units. The base SI unit for area is the square meter (m²). All other area units in the metric system can be derived from the square meter:
- Hectare (ha) = 10,000 square meters = 100 ares
- Square kilometer (km²) = 1,000,000 square meters = 10,000 ares
- Square centimeter (cm²) = 0.0001 square meters = 0.0001 ares
- Square millimeter (mm²) = 0.000001 square meters = 0.000001 ares
What are Ares Used For?
Ares are used in specific applications, particularly in land measurement and agriculture. Though not part of the SI system, they provide a convenient scale for certain measurements:
Land Surveying
In some European countries, land plots are measured in ares, especially for smaller parcels. For example, a small residential lot might be 5-10 ares.
Agriculture
Used to measure field sizes and crop yields. For instance, a small vineyard might cover 20 ares of land.
Real Estate
In some regions, property sizes are described in ares rather than hectares or square meters for medium-sized lots.
Historical Records
Many historical land records and cadastral maps use ares as the unit of measurement, requiring conversion for modern use.
Etymology and History
The word "are" comes from the Latin "area," meaning a level piece of ground. The unit was introduced in France in 1795 as part of the original metric system, defined as 100 square meters. It was intended to be a convenient unit for measuring land area, particularly for agricultural purposes.
When the metric system was restructured in 1960 to become the International System of Units (SI), the are was not included among the base or derived units. However, it remains accepted for use with SI units, particularly in countries that have not fully transitioned to hectares for land measurement. The related unit hectare (100 ares) is more commonly used today.
Frequently Asked Questions
Why is the are not an SI unit?
The are was not included in the International System of Units (SI) when it was formalized in 1960. The SI system chose to base area measurements on the square meter (m²) rather than introducing a separate unit for 100 m². However, the are remains accepted for use with SI units, especially in specific contexts like land measurement in some countries.
How do I convert ares to other units?
Use our are conversion calculators above, or multiply by the appropriate conversion factor. For example, to convert ares to square meters, multiply by 100; to convert ares to hectares, divide by 100. For detailed instructions on converting ares to hectares, visit our a to ha converter.
What's the difference between are and hectare?
A hectare is 100 times larger than an are. Specifically, 1 hectare equals 100 ares or 10,000 square meters. While both are accepted for use with SI units, hectares are more commonly used for measuring larger land areas like farms and forests.
Where are ares commonly used today?
Ares are still used in several European countries for land measurement, particularly in real estate listings and agricultural contexts. They're also found in historical documents and cadastral records. In most other contexts, hectares or square meters are preferred.
Is your are conversion tool free to use?
Yes, our are conversion calculator is completely free with no registration required. Simply enter your value, select your target unit, and get instant, accurate results. We believe precise measurement conversion should be accessible to everyone, from students learning about area units to professionals working with land measurements.
How accurate are the are conversions?
Our are converter provides highly accurate results based on internationally recognized conversion factors. Since 1 are is exactly 100 square meters, conversions to metric units are precise. Conversions to imperial units use standard conversion factors with appropriate precision for most practical applications.
