Worked example: 10 psi = 68.947573 kPa. A tire at 32 psi is 32 x 0.0689476 = 2.206 bar, which is 220.6 kPa. A blood pressure of 120 mmHg is 16.0 kPa.

Formula

pascals = value x unit factor (1 atm = 101,325 Pa, 1 bar = 100,000 Pa, 1 psi = 6,894.757293168 Pa, 1 mmHg = 133.322387415 Pa)

Understanding Pressure Conversion

Pressure is force per area. The SI unit is the pascal, which is tiny, so kilopascals and bar are more common. Tire gauges in the US read pounds per square inch (psi) while much of the world uses bar or kPa. Weather reports use hectopascals or inches of mercury, and blood pressure is measured in millimeters of mercury. Standard atmospheric pressure is exactly 101,325 pascals.

Tips and Best Practices

  • 1One bar is about 14.504 psi and 100 kPa.
  • 2Standard atmosphere is 14.696 psi, 1.01325 bar or 760 mmHg.
  • 3Check whether a gauge reads absolute pressure or gauge pressure (relative to the air around you).

Real-World Example

A tire at 32 psi is 32 x 0.0689476 = 2.206 bar, which is 220.6 kPa. A blood pressure of 120 mmHg is 16.0 kPa.

Common Mistakes to Avoid

  • Confusing gauge and absolute pressure, which differ by about 14.7 psi at sea level.
  • Mixing kPa and MPa, a factor of 1,000.
  • Treating torr and mmHg as different; they agree to within a few parts per billion for practical use.
