About Hectare
The hectare is 10,000 square meters (100 m × 100 m). It is widely used for farmland, forests, and land registration outside the US.
About Are
The are is 100 m². It is a metric land-area unit that sits between square meters and hectares.
How to convert hectares to ares
1 hectare is equal to 100 are:
1 ha = (10000 m² ÷ 100 m²) a = 100 a
Each hectare is defined as 10000 m² and each are as 100 m², so one ha equals 10000 ÷ 100 a = 100 a.
Let a(ha) be the numeric value of the same area measured in Hectare (ha), and a(a) the value in Are (a). Then:
a(a) = a(ha) × (10000 / 100)
Equivalently, divide by how many ha fit into one a (m² per a divided by m² per ha):
a(a) = a(ha) ÷ 0.01
Or: are = hectare ÷ 0.01
Examples
Example #1: Convert 20 ha to are
20 ha = 20 ha × (10000/100) a = 2000 a
20 ha = 20 ha ÷ 0.01 = 2000 a
Example #2: Convert 50 ha to are
50 ha = 50 ha × (10000/100) a = 5000 a
50 ha = 50 ha ÷ 0.01 = 5000 a
Summary
To convert Hectare to Are, multiply the value in ha by the ratio of square meters per ha divided by square meters per a. Equivalently: value_a = value_ha × (10000 / 100). Numerically, 1 ha equals 100 a.
Relationship context
Both units are metric (SI) and tied to the square meter. Conversions use exact ratios from their m² definitions. The factor from Hectare to Are is 1.000000e+2 (1 ha = 100 a).
