Convert ares to hectares and hectares to ares. Visual 10×10 are grid, metric area hierarchy, quick conversion table, and square feet/meters output.
The are (a) is a metric unit of area equal to 100 square meters — or a 10×10 meter square. While less commonly used today than the hectare, the are remains the foundation of metric land measurement, and understanding the are-hectare relationship is essential for interpreting land records in many countries.
Exactly 100 ares make one hectare. This simple factor of 100 fits naturally into the decimal metric system: 1 ca (centiare) = 1 m², 1 are = 100 m², 1 hectare = 10,000 m². This converter instantly converts between ares and hectares, and also shows results in square meters, square feet, acres, and centiares.
The visual grid makes the relationship crystal clear: each colored square represents one are, and a full 10×10 grid equals one hectare. This tool is valuable for interpreting European property documents, agricultural measurements, and cadastral records where ares are commonly used. It is particularly useful when translating legal descriptions into units familiar to international buyers and analysts.
The are is still used in European property records, French-speaking countries, and some Asian land registries. Converting between ares and hectares — and understanding where they sit in the metric area hierarchy — matters for international real estate, translation, and archival research where precision and consistency are essential in legal and technical workflows.
Ares to Hectares: ha = ares ÷ 100 Hectares to Ares: ares = ha × 100 1 are = 100 m² = 1,076.39 ft² 1 hectare = 100 ares = 10,000 m²
Result: 0.5 hectares = 5,000 m²
50 ares ÷ 100 = 0.5 hectares. Since 1 are = 100 m², then 50 ares = 5,000 m² = 53,820 ft². This is about 1.24 acres.
The metric system organizes area units in powers of 10: centiare (1 m²) → are (100 m²) → decare (1,000 m²) → hectare (10,000 m²) → square kilometer (1,000,000 m²). This decimal structure makes conversion trivial — just move the decimal point.
The are was defined during the French Revolution as part of the new metric system. It was intended to replace the many inconsistent land measures used across French provinces. While the hectare became more practical for large-scale use, the are persisted in property law.
French notarial acts express area as "X ha Y a Z ca" — hectares, ares, and centiares. For example, "2 ha 35 a 17 ca" means 2 hectares + 35 ares + 17 centiares = 23,517 m². Understanding this notation is essential for anyone dealing with European real estate transactions.
Exactly 100. A hectare = 100 ares = 10,000 m². The prefix "hecto-" means 100.
An are (symbol: a) is a metric unit of area equal to 100 square meters, or a 10×10 meter square. It was introduced with the metric system in the 1790s.
Yes, primarily in property records, particularly in France, Belgium, Switzerland, and several other European and Asian countries. It is also used in some land registration systems. However, for most practical purposes, the hectare has replaced it.
A centiare (ca) = 1/100 of an are = 1 square meter. It is used in French property law to express precise areas without fractions.
An are (100 m²) is much smaller than an acre (4,047 m²). One acre = about 40.47 ares. Despite the similar names, they have different origins and sizes.
A decare (daa) = 10 ares = 1,000 m². It is commonly used in Turkey, Norway, and parts of Eastern Europe for agricultural land measurement.
