PSI CONVERSION FACTORS
 
To PSI From PSI
psi = in. of H2O x (3.6127 x 10-2) in. of H2O = psi x 27.68
psi = in. of Hg x (0.49118) in. of Hg = psi x 2.036
psi = mm of H2 x (1.4223 x 10-3) mm of H2O = psi x 703.1
psi = mm of Hg x (1.9339 x 10-2) mm of Hg = psi x 51.71
psi = cm of H2O x (14.223 x 6-3) cm of H2O = psi x 70.3
psi = kg/cm2 x (14.223) kg/cm2 = psi x .0703
psi = bar x (14.503) bar = psi x .0689
psi = mbar x (1.4503 x 10-2) mbar = psi x 68.95
psi = Pa x (1.4503 x 10-4) Pa = psi x 6895
psi = kPa x (1.4503 x 10-1) kPa = psi x 6.895
