How the conversion works
Multiply by 0.0029890669 to go from foot 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 foot of water column — 1 MPa = 334.5525656 ft H₂O.
