About Square Centimeter
The square centimeter is one ten-thousandth of a square meter. Small objects, paper sizes, and biology use square centimeters.
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 centimeters to ares
1 square centimeter is equal to 0.000001 are:
1 cm2 = (0.0001 m² ÷ 100 m²) a = 0.000001 a
Each square centimeter is defined as 0.0001 m² and each are as 100 m², so one cm2 equals 0.0001 ÷ 100 a = 0.000001 a.
Let a(cm2) be the numeric value of the same area measured in Square Centimeter (cm2), and a(a) the value in Are (a). Then:
a(a) = a(cm2) × (0.0001 / 100)
Equivalently, divide by how many cm2 fit into one a (m² per a divided by m² per cm2):
a(a) = a(cm2) ÷ 1000000
Or: are = square centimeter ÷ 1000000
Examples
Example #1: Convert 20 cm2 to are
20 cm2 = 20 cm2 × (0.0001/100) a = 0.00002 a
20 cm2 = 20 cm2 ÷ 1000000 = 0.00002 a
Example #2: Convert 50 cm2 to are
50 cm2 = 50 cm2 × (0.0001/100) a = 0.00005 a
50 cm2 = 50 cm2 ÷ 1000000 = 0.00005 a
Summary
To convert Square Centimeter to Are, multiply the value in cm2 by the ratio of square meters per cm2 divided by square meters per a. Equivalently: value_a = value_cm2 × (0.0001 / 100). Numerically, 1 cm2 equals 0.000001 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 Centimeter to Are is 1.000000e-6 (1 cm2 = 0.000001 a).
