inH2O to ksi converter
1 inH2O = 3.61263 × 10-5 ksi
And 1 ksi = 27,680.7 inH2O. Inches of water column to kilopounds per square inch.
Formula
ksi = inH2O × 3.61263 × 10^-5
A reading of 15 inH2O is 15 × 3.61263 × 10^-5 = 0.000541894 ksi.

About these units
inH2O (inches of water column): Low duct and furnace pressures, at the conventional 4 °C water reference.
ksi (kilopounds per square inch): US structural and material strength: 1 ksi = 1,000 psi.
Gauge pressure (psig, barg) is measured relative to the surrounding atmosphere; absolute pressure (psia, bara) is relative to vacuum. Converting units never changes that reference: absolute = gauge + about 14.696 psi (1.01325 bar) at sea level. Stress uses the same units: 1 MPa = 1 N/mm².
