Convert Hectares to Square Centimeters (ha to cm2)
1 hectare (ha) = 100000000 square centimeters (cm²). 1 cm² = 1 × 10⁻⁸ ha. Example: 15 ha = 15 × 100000000 = 1500000000 cm².

How to Convert Hectare to Square Centimeter
- 1 ha = 100000000 cm²
- 1 cm² = 1 × 10⁻⁸ ha
- Example: convert 15 ha to cm²: 15 ha = 15 × 100000000 cm² = 1500000000 cm²
Formula
cm² = ha × 100000000
Derivation from SI units:
- 1 ha = 100 m × 100 m = 10 000 m² (a non-SI unit accepted for use with the SI)
- 1 cm² = (0.01 m)² = 10⁻⁴ m²
- 1 ha = 10000 m² ÷ 0.0001 m² per cm² = 100000000 cm²
Both units are defined exactly, so the factor is exact. Hectare definition: hectare; Square Centimeter definition: square centimeter.
Worked examples
- A reading of 1 ha converts to 100000000 cm².
1 ha × 100000000 = 100000000 cm² - A value of 20 ha is 2000000000 cm².
20 ha × 100000000 = 2000000000 cm²

Where it's used
Hectares are used for farm and forest land, while square centimeters appear in test areas in air-permeability testing (ISO 9237: 5, 10, 20, 50, 100 cm²; ASTM D737: 38.3 cm²). Both measure area, so the conversion is a fixed factor.
