Conversion Formula

The formula to convert kpa to psi is psi = kpa * 0.145038. This works because 1 kilopascal equals 0.145038 pounds per square inch. The conversion factor comes from the definition of these units; 1 kpa equals 1000 pascals, and 1 psi equals 6894.76 pascals. Dividing 1 by 6894.76 gives the conversion factor.

For example, with 145 kpa, multiply 145 by 0.145038:

• 145 * 0.145038 = 21.05211
• Result rounded to four decimal places is 21.0521 psi.

Conversion Example

• Convert 100 kpa:
  • Multiply 100 by 0.145038
  • 100 * 0.145038 = 14.5038 psi
• Convert 200 kpa:
  • 200 * 0.145038 = 29.0076 psi
• Convert 50 kpa:
  • 50 * 0.145038 = 7.2519 psi
• Convert 300 kpa:
  • 300 * 0.145038 = 43.5114 psi
• Convert 75 kpa:
  • 75 * 0.145038 = 10.8778 psi
