Convert Centimeters of Water to kgf/cm²
1 centimeter of water (cmH₂O) = 0.001 kilograms-force per square centimetre (kgf/cm²). 1 kgf/cm² = 1000 cmH₂O. Example: 15 cmH₂O = 15 × 0.001 = 0.015 kgf/cm².

How to Convert Centimeter of Water to Kilogram-force per Square Centimetre
- 1 cmH₂O = 0.001 kgf/cm²
- 1 kgf/cm² = 1000 cmH₂O
- Example: convert 15 cmH₂O to kgf/cm²: 15 cmH₂O = 15 × 0.001 kgf/cm² = 0.015 kgf/cm²
Reference conditions. cmH₂O: Conventional water column: ρ = 1000 kg/m³ and gₙ = 9.80665 m/s² (≈ water at 4 °C).
Formula
kgf/cm² = cmH₂O ÷ 1000
Derivation from SI units:
- 1 cmH₂O = 1000 kg/m³ × 9.80665 m/s² × 0.01 m = 98.0665 Pa
- 1 kgf/cm² = 9.80665 N ÷ 10⁻⁴ m² = 98 066.5 Pa (exact), also called the technical atmosphere (at)
- 1 cmH₂O = 98.0665 Pa ÷ 98066.5 Pa per kgf/cm² = 0.001 kgf/cm²
Both units are defined exactly, so the factor is exact. Centimeter of Water definition: centimeter of water; Kilogram-force per Square Centimetre definition: kilogram-force per square centimetre.
Worked examples
- A reading of 6 cmH₂O converts to 0.006 kgf/cm².
6 cmH₂O × 0.001 = 0.006 kgf/cm² - A value of 30 cmH₂O is 0.03 kgf/cm².
30 cmH₂O × 0.001 = 0.03 kgf/cm²

Where it's used
Centimeters of Water are used for mechanical ventilation (PEEP 5–10 cmH₂O, plateau pressure under 30 cmH₂O), while kilograms-force per square centimetre appear in pressure gauges in India, Japan and Latin America. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
