How the conversion works
Multiply by 0.004014630787 to go from pascal 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 pascal — 1 in w.g. = 249.0889083 Pa.
