How the conversion works
Multiply by 401.4630787 to go from bar 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 bar — 1 in w.g. = 0.002490889083 bar.
