Convert Kilograms-force per Square Millimetre to cmH₂O
1 kilogram-force per square millimetre (kgf/mm²) = 100000 centimeters of water (cmH₂O). 1 cmH₂O = 0.00001 kgf/mm². Example: 15 kgf/mm² = 15 × 100000 = 1500000 cmH₂O.

How to Convert Kilogram-force per Square Millimetre to Centimeter of Water
- 1 kgf/mm² = 100000 cmH₂O
- 1 cmH₂O = 0.00001 kgf/mm²
- Example: convert 15 kgf/mm² to cmH₂O: 15 kgf/mm² = 15 × 100000 cmH₂O = 1500000 cmH₂O
Reference conditions. cmH₂O: Conventional water column: ρ = 1000 kg/m³ and gₙ = 9.80665 m/s² (≈ water at 4 °C).
Formula
cmH₂O = kgf/mm² × 100000
Derivation from SI units:
- 1 kgf/mm² = 9.80665 N ÷ 1 mm² = 9.80665 MPa (exact)
- 1 cmH₂O = 1000 kg/m³ × 9.80665 m/s² × 0.01 m = 98.0665 Pa
- 1 kgf/mm² = 9806650 Pa ÷ 98.0665 Pa per cmH₂O = 100000 cmH₂O
Both units are defined exactly, so the factor is exact. Kilogram-force per Square Millimetre definition: kilogram-force per square millimetre; Centimeter of Water definition: centimeter of water.
Worked examples
- A reading of 24 kgf/mm² converts to 2400000 cmH₂O.
24 kgf/mm² × 100000 = 2400000 cmH₂O - A value of 50 kgf/mm² is 5000000 cmH₂O.
50 kgf/mm² × 100000 = 5000000 cmH₂O

Where it's used
Kilograms-force per Square Millimetre are used for tensile strength in older JIS and GB steel standards, while centimeters of water appear in mechanical ventilation (PEEP 5–10 cmH₂O, plateau pressure under 30 cmH₂O). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
