How to Convert Gigapascal to Inch of Water (60 °F)
- 1 GPa = 4018646.52 inH₂O (60 °F)
- 1 inH₂O (60 °F) = 2.4884 × 10⁻⁷ GPa
- Example: convert 15 GPa to inH₂O (60 °F): 15 GPa = 15 × 4018646.52 inH₂O (60 °F) = 60279697.8 inH₂O (60 °F)
Reference conditions. inH₂O (60 °F): Water at 60 °F (15.6 °C), density ≈ 999.0 kg/m³, standard gravity. NIST value, 5 significant figures.
Formula
inH₂O (60 °F) = GPa × 4018646.519852
Derivation from SI units:
- 1 GPa = 10⁹ Pa = 1000 MPa = 1 kN/mm²
- 1 inH₂O (60 °F) ≈ 999.0 kg/m³ × 9.80665 m/s² × 0.0254 m ≈ 248.84 Pa
- 1 GPa = 1000000000 Pa ÷ 248.84 Pa per inH₂O (60 °F) = 4018646.519852 inH₂O (60 °F)
One unit is a measured value, so the factor is approximate. Gigapascal definition: gigapascal; Inch of Water (60 °F) definition: inch of water (60 °F).
Worked examples
- A reading of 10 GPa converts to 40186465.2 inH₂O (60 °F).
10 GPa × 4018646.52 = 40186465.2 inH₂O (60 °F) - A value of 190 GPa is 763542838.8 inH₂O (60 °F).
190 GPa × 4018646.52 = 763542838.8 inH₂O (60 °F)

Where it's used
Gigapascals are used for young's modulus and shear modulus of metals, ceramics and composites, while inches of water (60 °F) appear in older US gas-industry and flow-meter references. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
