How the conversion works

Multiply by 13.59510009 to go from inch of mercury 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 inch of mercury — 1 in w.g. = 0.07355591303 inHg.
