How to Convert Megapascal to Inch of Water (60 °F)
- 1 MPa = 4018.64652 inH₂O (60 °F)
- 1 inH₂O (60 °F) = 0.00024884 MPa
- Example: convert 15 MPa to inH₂O (60 °F): 15 MPa = 15 × 4018.64652 inH₂O (60 °F) = 60279.6978 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) = MPa × 4018.646519852
Derivation from SI units:
- 1 MPa = 10⁶ Pa = 1 N/mm²
- 1 inH₂O (60 °F) ≈ 999.0 kg/m³ × 9.80665 m/s² × 0.0254 m ≈ 248.84 Pa
- 1 MPa = 1000000 Pa ÷ 248.84 Pa per inH₂O (60 °F) = 4018.646519852 inH₂O (60 °F)
One unit is a measured value, so the factor is approximate. Megapascal definition: megapascal; Inch of Water (60 °F) definition: inch of water (60 °F).
Worked examples
- A reading of 2 MPa converts to 8037.29304 inH₂O (60 °F).
2 MPa × 4018.64652 = 8037.29304 inH₂O (60 °F) - A value of 30 MPa is 120559.3956 inH₂O (60 °F).
30 MPa × 4018.64652 = 120559.3956 inH₂O (60 °F)

Where it's used
Megapascals are used for concrete compressive strength (typically 20–50 MPa), 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.
