Pressure Unit Conversion Formula Quick Reference

Use this page for pressure unit conversion, converting pressure units, converting units of pressure, and tyre pressure unit conversion between psi, kPa, bar, Pa, MPa, atm, and mmHg. Formula: target value = source value x source-to-Pa factor / target-to-Pa factor.

1 bar

100,000 Pa = 100 kPa = 14.5038 psi

1 psi

6.89476 kPa = 0.0689476 bar

1 MPa

10 bar = 1,000 kPa

1 atm

101,325 Pa = 760 mmHg

pressure unit conversion

Convert values through the pascal base formula and compare common pressure units.

converting pressure units

Use the calculator for bar, psi, Pa, kPa, MPa, atm, mmHg, hPa, Torr, and kgf/cm².

tyre pressure unit conversion

Compare tyre pressure values between psi, kPa, and bar before checking a vehicle or bicycle specification.

32 psi tyre pressure

32 psi is about 220.6 kPa or 2.21 bar, a common tyre pressure conversion example.

Pressure units come up frequently when dealing with tire pressure, gas pressure, hydraulics, and more. Since different countries and industries use different units, conversion is often necessary.

1. Common Pressure Units

  • PSI (Pounds per Square Inch): US unit, used for tire pressure
  • Bar: European standard, 1 bar = 100 kPa
  • kPa (Kilopascal): International standard unit
  • atm (Atmosphere): Based on atmospheric pressure, 1 atm = 101.325 kPa
  • mmHg (Millimeters of Mercury): Used in medicine and meteorology
  • MPa (Megapascal): Used for high-pressure measurements

2. Quick Conversion Formulas

1 PSI = 0.0689 Bar = 6.895 kPa 1 Bar = 14.5 PSI = 100 kPa 1 kPa = 0.145 PSI = 0.01 Bar 1 atm = 14.7 PSI = 1.013 Bar = 101.325 kPa

Examples:

  • Tire pressure 32 PSI = 2.2 Bar = 220 kPa
  • 2.5 Bar = 36 PSI = 250 kPa

4. Everyday Applications

Tire Pressure:

  • Standard passenger car: 30-35 PSI (2.0-2.4 Bar)
  • SUV: 35-40 PSI (2.4-2.8 Bar)
  • Winter: 2-3 PSI above recommended pressure

Water Pressure:

  • Residential water supply: 2-4 Bar (30-60 PSI)
  • Ideal shower pressure: 1.5-2.5 Bar

Additional Tips

  • It is recommended to check tire pressure at least once a month
  • Pressure should be measured when tires are cold for accurate readings
  • Installing a unit conversion app on your phone is very convenient
  • Always check the unit displayed on the pressure gauge at a garage or gas station
