Convert Kilograms-force per Square Centimetre to mmH₂O
1 kilogram-force per square centimetre (kgf/cm²) = 10000 millimeters of water (mmH₂O). 1 mmH₂O = 0.0001 kgf/cm². Example: 15 kgf/cm² = 15 × 10000 = 150000 mmH₂O.

How to Convert Kilogram-force per Square Centimetre to Millimeter of Water
- 1 kgf/cm² = 10000 mmH₂O
- 1 mmH₂O = 0.0001 kgf/cm²
- Example: convert 15 kgf/cm² to mmH₂O: 15 kgf/cm² = 15 × 10000 mmH₂O = 150000 mmH₂O
Reference conditions. mmH₂O: Conventional water column: ρ = 1000 kg/m³ and gₙ = 9.80665 m/s² (≈ water at 4 °C).
Formula
mmH₂O = kgf/cm² × 10000
Derivation from SI units:
- 1 kgf/cm² = 9.80665 N ÷ 10⁻⁴ m² = 98 066.5 Pa (exact), also called the technical atmosphere (at)
- 1 mmH₂O = 1000 kg/m³ × 9.80665 m/s² × 0.001 m = 9.80665 Pa
- 1 kgf/cm² = 98066.5 Pa ÷ 9.80665 Pa per mmH₂O = 10000 mmH₂O
Both units are defined exactly, so the factor is exact. Kilogram-force per Square Centimetre definition: kilogram-force per square centimetre; Millimeter of Water definition: millimeter of water.
Worked examples
- A reading of 7 kgf/cm² converts to 70000 mmH₂O.
7 kgf/cm² × 10000 = 70000 mmH₂O - A value of 100 kgf/cm² is 1000000 mmH₂O.
100 kgf/cm² × 10000 = 1000000 mmH₂O

Where it's used
Kilograms-force per Square Centimetre are used for pressure gauges in India, Japan and Latin America, while millimeters of water appear in fan static pressure and duct design in Asia and Europe. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
