About Are
The are is 100 m². It is a metric land-area unit that sits between square meters and hectares.
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.
How to convert ares to hectares
1 are is equal to 0.01 hectare:
1 a = (100 m² ÷ 10000 m²) ha = 0.01 ha
Each are is defined as 100 m² and each hectare as 10000 m², so one a equals 100 ÷ 10000 ha = 0.01 ha.
Let a(a) be the numeric value of the same area measured in Are (a), and a(ha) the value in Hectare (ha). Then:
a(ha) = a(a) × (100 / 10000)
Equivalently, divide by how many a fit into one ha (m² per ha divided by m² per a):
a(ha) = a(a) ÷ 100
Or: hectare = are ÷ 100
Examples
Example #1: Convert 20 a to hectare
20 a = 20 a × (100/10000) ha = 0.2 ha
20 a = 20 a ÷ 100 = 0.2 ha
Example #2: Convert 50 a to hectare
50 a = 50 a × (100/10000) ha = 0.5 ha
50 a = 50 a ÷ 100 = 0.5 ha
Summary
To convert Are to Hectare, multiply the value in a by the ratio of square meters per a divided by square meters per ha. Equivalently: value_ha = value_a × (100 / 10000). Numerically, 1 a equals 0.01 ha.
Relationship context
Both units are metric (SI) and tied to the square meter. Conversions use exact ratios from their m² definitions. The factor from Are to Hectare is 1.000000e-2 (1 a = 0.01 ha).
