How to Convert Inch of Water (60 °F) to Megapascal
- 1 inH₂O (60 °F) = 0.00024884 MPa
- 1 MPa = 4018.64652 inH₂O (60 °F)
- Example: convert 15 inH₂O (60 °F) to MPa: 15 inH₂O (60 °F) = 15 × 0.00024884 MPa = 0.0037326 MPa
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
MPa = inH₂O (60 °F) × 0.00024884
or MPa = inH₂O (60 °F) ÷ 4018.646519852
Derivation from SI units:
- 1 inH₂O (60 °F) ≈ 999.0 kg/m³ × 9.80665 m/s² × 0.0254 m ≈ 248.84 Pa
- 1 MPa = 10⁶ Pa = 1 N/mm²
- 1 inH₂O (60 °F) = 248.84 Pa ÷ 1000000 Pa per MPa = 0.00024884 MPa
One unit is a measured value, so the factor is approximate. Inch of Water (60 °F) definition: inch of water (60 °F); Megapascal definition: megapascal.
Worked examples
- A reading of 0.5 inH₂O (60 °F) converts to 0.00012442 MPa.
0.5 inH₂O (60 °F) × 0.00024884 = 0.00012442 MPa - A value of 7 inH₂O (60 °F) is 0.00174188 MPa.
7 inH₂O (60 °F) × 0.00024884 = 0.00174188 MPa

Where it's used
Inches of Water (60 °F) are used for older US gas-industry and flow-meter references, while megapascals appear in concrete compressive strength (typically 20–50 MPa). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
