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

• 1 ftH2O = 0.4335 psi = 62.43 lbs/ft2
• 1 psi (lb/in2) = 144 psf (lbf/ft2) = 6894.8 Pa (N/m2) = 6.895x10-3 N/mm2 = 6.895x10-2 bar = 27.71 in H2O at 62oF (16.7oC) = 703.1 mm H2O at 62oF (16.7oC) = 2.0416 in mercury at 62oF (16.7oC) = 51.8 mm mercury at 62oF (16.7oC) = 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 ftH2O = 27.7 psi (lb/in2)
