How the conversion works

Multiply by 12 to go from foot of water column 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 foot of water column — 1 in w.g. = 0.08333333332 ft H₂O.
