Conversion Factors
psi = inches of H2O x (3.6127 x 10-2)
inches of H2O = psi x 27.68
psi = mm of H2O x (1.4223 x 10-3)
mm of H2O = psi x 703.1
psi = cm of H2O x (14.223 x 10-3)
cm of H2O = psi x 70.3
psi = bar x (14.503)
bar = psi x 0.0689
psi = lbs/ft2 x (6.9444 x 10-3)
lbs/ft2 = psi x 144
psi = mbar x (1.4503 x 10-2)
mbar = psi x (68.9513)
psi = Pascals x (1.4503 x 10-4)
Pascals = psi x (6.895 x 103)
All H2O conversion factors are @ 4°C
