How the conversion works

Multiply by 0.0002490889083 to go from inch of water column to megapascal, 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? megapascal to inch of water column — 1 MPa = 4,014.630787 in w.g..
