foot of water column: Head in feet of water is only equal to pressure when the fluid is water. A centrifugal pump develops a head in feet that is nearly independent of fluid density, but the pressure it produces is proportional to density, so pumping a fluid of specific gravity 1.3 gives 30 percent more pressure for the same head. Also check the reference temperature: values quoted at 39.2 °F, 60 °F and 68 °F differ in the fourth digit. Full definition →
Multiply by 0.0003345525656 to go from pascal to foot 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.
