Pressure Converter Guide
Convert pressure between PSI, bar, kilopascals, atmospheres, and millimeters of mercury — useful for tires, weather, and engineering. Enter a value and pick the units.
1 bar = 14.5038 PSI · 1 atm = 14.696 PSI · 1 PSI = 6.895 kPa · 1 bar = 100 kPa.
How Do I Convert PSI to Bar?
Each unit is defined against the pascal. To convert PSI to bar, divide by 14.5038; to go the other way, multiply. For example, 32 PSI ÷ 14.5038 = 2.21 bar — a typical tire pressure.
