How to Convert ksi to Inch of Water (60 °F)
- 1 ksi = 27707.5924 inH₂O (60 °F)
- 1 inH₂O (60 °F) = 0.00003609119066 ksi
- Example: convert 15 ksi to inH₂O (60 °F): 15 ksi = 15 × 27707.5924 inH₂O (60 °F) = 415613.886 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) = ksi × 27707.59240142
Derivation from SI units:
- 1 ksi = 1000 psi = 1 kip/in² = 6.894757293168 MPa
- 1 inH₂O (60 °F) ≈ 999.0 kg/m³ × 9.80665 m/s² × 0.0254 m ≈ 248.84 Pa
- 1 ksi = 6894757.293168 Pa ÷ 248.84 Pa per inH₂O (60 °F) = 27707.59240142 inH₂O (60 °F)
One unit is a measured value, so the factor is approximate. ksi definition: ksi; Inch of Water (60 °F) definition: inch of water (60 °F).
Worked examples
- A reading of 20 ksi converts to 554151.848 inH₂O (60 °F).
20 ksi × 27707.5924 = 554151.848 inH₂O (60 °F) - A value of 65 ksi is 1800993.506 inH₂O (60 °F).
65 ksi × 27707.5924 = 1800993.506 inH₂O (60 °F)
