How to Convert Inch of Water (60 °F) to psi
- 1 inH₂O (60 °F) = 0.03609119066 psi
- 1 psi = 27.7075924 inH₂O (60 °F)
- Example: convert 15 inH₂O (60 °F) to psi: 15 inH₂O (60 °F) = 15 × 0.03609119066 psi = 0.5413678599 psi
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
psi = inH₂O (60 °F) × 0.03609119065679
or psi = inH₂O (60 °F) ÷ 27.70759240142
Derivation from SI units:
- 1 inH₂O (60 °F) ≈ 999.0 kg/m³ × 9.80665 m/s² × 0.0254 m ≈ 248.84 Pa
- 1 psi = 1 lbf/in² = (0.45359237 kg × 9.80665 m/s²) ÷ (0.0254 m)² = 6894.757293168 Pa
- 1 inH₂O (60 °F) = 248.84 Pa ÷ 6894.757293168 Pa per psi = 0.03609119065679 psi
One unit is a measured value, so the factor is approximate. Inch of Water (60 °F) definition: inch of water (60 °F); psi definition: psi.
Worked examples
- A reading of 0.5 inH₂O (60 °F) converts to 0.01804559533 psi.
0.5 inH₂O (60 °F) × 0.03609119066 = 0.01804559533 psi - A value of 7 inH₂O (60 °F) is 0.2526383346 psi.
7 inH₂O (60 °F) × 0.03609119066 = 0.2526383346 psi

Where it's used
Inches of Water (60 °F) are used for older US gas-industry and flow-meter references, while psi appear in tyre pressure in the United States (about 30–35 psi for cars). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
