How to Convert Gigapascal to Centimeter of Water
- 1 GPa = 10197162.13 cmH₂O
- 1 cmH₂O = 9.80665 × 10⁻⁸ GPa
- Example: convert 15 GPa to cmH₂O: 15 GPa = 15 × 10197162.13 cmH₂O = 152957431.9 cmH₂O
Reference conditions. cmH₂O: Conventional water column: ρ = 1000 kg/m³ and gₙ = 9.80665 m/s² (≈ water at 4 °C).
Formula
cmH₂O = GPa × 10197162.12978
Derivation from SI units:
- 1 GPa = 10⁹ Pa = 1000 MPa = 1 kN/mm²
- 1 cmH₂O = 1000 kg/m³ × 9.80665 m/s² × 0.01 m = 98.0665 Pa
- 1 GPa = 1000000000 Pa ÷ 98.0665 Pa per cmH₂O = 10197162.12978 cmH₂O
Both units are defined exactly, so the factor is exact. Gigapascal definition: gigapascal; Centimeter of Water definition: centimeter of water.
Worked examples
- A reading of 10 GPa converts to 101971621.3 cmH₂O.
10 GPa × 10197162.13 = 101971621.3 cmH₂O - A value of 190 GPa is 1937460805 cmH₂O.
190 GPa × 10197162.13 = 1937460805 cmH₂O

Where it's used
Gigapascals are used for young's modulus and shear modulus of metals, ceramics and composites, 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.
