hectare to are (ha to a) – How to convert ha to a
The hectare to are conversion is one of the simplest in the metric system. Both units were introduced during the French Revolution as part of the push for a unified and logical measurement system. Today, the hectare is the most widely used land unit in global agriculture, forestry, and statistics, while the are has mostly faded from everyday use but still exists in historical records. Let’s break down the two units and see how they connect.
What is a Hectare?
A hectare (ha) is the standard metric unit for large areas of land.
-
Definition: 1 ha = 10,000 m².
-
Relation: 1 ha = 100 ares.
-
Use: Commonly used in agriculture, forestry, environmental science, and global statistics.
What is an Are?
An are (a) is a smaller metric unit of area.
-
Definition: 1 a = 100 m².
-
History: Adopted in 1795 during the metric reforms of revolutionary France.
-
Usage: Once popular, especially for property deeds and smaller land plots, though now largely replaced by the hectare.
Conversion Formula: Hectare to Are
This conversion couldn’t be easier:
1 ha = 100 a
Example:7 ha × 100 = 700 a
This makes the hectare-to-are conversion one of the most straightforward in the entire metric system.

Did you know?
-
The are was one of the original metric units, created alongside the meter and liter during France’s reforms in 1795.
-
The hectare, though not part of the SI system, is widely recognized internationally and remains the go-to for agricultural and forestry statistics.
-
In some European countries, older rural property deeds still list areas in ares, especially for gardens and small plots.
-
Large urban parks are often measured in hectares, while smaller areas inside those parks may still be described in ares.
From the French Revolution to Modern Farming
When the French Revolution brought sweeping changes, measurement reform was high on the agenda. The old patchwork of local systems created confusion, so leaders introduced a universal metric system. Among its early units was the are, equal to 100 square meters—perfect for small land holdings.
But as land management scaled up, the hectare, equal to 100 ares, quickly took over. Farmers, foresters, and governments needed a larger and more practical measure. By the 19th century, the hectare had spread throughout Europe and later the world, while the are became secondary.
Even so, the relationship between hectares and ares is a reminder of the system’s original simplicity: everything builds neatly from the square meter upward.
