About Are
The are is 100 m². It is a metric land-area unit that sits between square meters and hectares.
About Decare
The decare equals 1,000 m² (10 ares). It is used in agriculture and land records in parts of Europe and the Middle East.
How to convert ares to decares
1 are is equal to 0.1 decare:
1 a = (100 m² ÷ 1000 m²) daa = 0.1 daa
Each are is defined as 100 m² and each decare as 1000 m², so one a equals 100 ÷ 1000 daa = 0.1 daa.
Let a(a) be the numeric value of the same area measured in Are (a), and a(daa) the value in Decare (daa). Then:
a(daa) = a(a) × (100 / 1000)
Equivalently, divide by how many a fit into one daa (m² per daa divided by m² per a):
a(daa) = a(a) ÷ 10
Or: decare = are ÷ 10
Examples
Example #1: Convert 20 a to decare
20 a = 20 a × (100/1000) daa = 2 daa
20 a = 20 a ÷ 10 = 2 daa
Example #2: Convert 50 a to decare
50 a = 50 a × (100/1000) daa = 5 daa
50 a = 50 a ÷ 10 = 5 daa
Summary
To convert Are to Decare, multiply the value in a by the ratio of square meters per a divided by square meters per daa. Equivalently: value_daa = value_a × (100 / 1000). Numerically, 1 a equals 0.1 daa.
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 Decare is 1.000000e-1 (1 a = 0.1 daa).
