How the conversion works
Multiply by 27.6799049 to go from pound per square inch to inch of water column, or divide by it to go back. Every conversion on this site routes through the SI value (Pa) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? inch of water column to pound per square inch — 1 in w.g. = 0.03612729175 psi.
