About Square Meter
The square meter is the SI derived unit of area. Floor plans, building codes, and science typically use square meters.
About Are
The are is 100 m². It is a metric land-area unit that sits between square meters and hectares.
How to convert square meters to ares
1 square meter is equal to 0.01 are:
1 m2 = (1 m² ÷ 100 m²) a = 0.01 a
Each square meter is defined as 1 m² and each are as 100 m², so one m2 equals 1 ÷ 100 a = 0.01 a.
Let a(m2) be the numeric value of the same area measured in Square Meter (m2), and a(a) the value in Are (a). Then:
a(a) = a(m2) × (1 / 100)
Equivalently, divide by how many m2 fit into one a (m² per a divided by m² per m2):
a(a) = a(m2) ÷ 100
Or: are = square meter ÷ 100
Examples
Example #1: Convert 20 m2 to are
20 m2 = 20 m2 × (1/100) a = 0.2 a
20 m2 = 20 m2 ÷ 100 = 0.2 a
Example #2: Convert 50 m2 to are
50 m2 = 50 m2 × (1/100) a = 0.5 a
50 m2 = 50 m2 ÷ 100 = 0.5 a
Summary
To convert Square Meter to Are, multiply the value in m2 by the ratio of square meters per m2 divided by square meters per a. Equivalently: value_a = value_m2 × (1 / 100). Numerically, 1 m2 equals 0.01 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 Square Meter to Are is 1.000000e-2 (1 m2 = 0.01 a).
