About Square Centimeter
The square centimeter is one ten-thousandth of a square meter. Small objects, paper sizes, and biology use square centimeters.
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 square centimeters to hectares
1 square centimeter is equal to 1.00000000e-8 hectare:
1 cm2 = (0.0001 m² ÷ 10000 m²) ha = 1.00000000e-8 ha
Each square centimeter is defined as 0.0001 m² and each hectare as 10000 m², so one cm2 equals 0.0001 ÷ 10000 ha = 1.00000000e-8 ha.
Let a(cm2) be the numeric value of the same area measured in Square Centimeter (cm2), and a(ha) the value in Hectare (ha). Then:
a(ha) = a(cm2) × (0.0001 / 10000)
Equivalently, divide by how many cm2 fit into one ha (m² per ha divided by m² per cm2):
a(ha) = a(cm2) ÷ 1.00000000e+8
Or: hectare = square centimeter ÷ 1.00000000e+8
Examples
Example #1: Convert 20 cm2 to hectare
20 cm2 = 20 cm2 × (0.0001/10000) ha = 0.0000002 ha
20 cm2 = 20 cm2 ÷ 1.00000000e+8 = 0.0000002 ha
Example #2: Convert 50 cm2 to hectare
50 cm2 = 50 cm2 × (0.0001/10000) ha = 0.0000005 ha
50 cm2 = 50 cm2 ÷ 1.00000000e+8 = 0.0000005 ha
Summary
To convert Square Centimeter to Hectare, multiply the value in cm2 by the ratio of square meters per cm2 divided by square meters per ha. Equivalently: value_ha = value_cm2 × (0.0001 / 10000). Numerically, 1 cm2 equals 1e-8 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 Square Centimeter to Hectare is 1.000000e-8 (1 cm2 = 1e-8 ha).
