Water Pressure vs. Head

Pressure in pounds per square inch (psi) vs. head in feet of water (ft_h2o).

Convert from Pressure - Pounds per Square Inch (psi) to Head of Water in Feet (ft_h2o)

Convert from Head - Water Feet to Pressure in Pounds per Square Inch

1 ft_H2O = 0.4335 psi = 62.43 lbs/ft²
1 psi (lb/in²) = 144 psf (lb_f/ft²) = 6894.8 Pa (N/m²) = 6.895x10^-3 N/mm² = 6.895x10^-2 bar = 27.71 in H₂O at 62^oF (16.7^oC) = 703.1 mm H₂O at 62^oF (16.7^oC) = 2.0416 in mercury at 62^oF (16.7^oC) = 51.8 mm mercury at 62^oF (16.7^oC) = 703.6 kg/m² = 0.06895 atm = 2.307 Ft. H₂O = 16 ounces

Example - Convert from Head to Pressure

A head of 64 ft can be converted to pressure by using the second table:

64 ft_H2O = 27.7 psi (lb/in²)
