How to Convert Pressure Units

To perform a conversion, look up the target unit's conversion factor relative to the base unit (pascal). Below are the exact mathematical formulas for the most common pressure unit pairs:

PSI (Pounds/sq in) to Bar bar = psi × 0.068947573
Bar to PSI (Pounds/sq in) psi = bar × 14.50377378
