Conversion Formula

The formula to convert kpa to psi is: psi = kpa × 0.145038. This works because pressure units are based on different systems, with 1 kilopascal being a metric unit and pounds per square inch being imperial. Multiplying by 0.145038 adjusts the value to psi.

For example, converting 100 kpa: 100 × 0.145038 = 14.5038 psi. This calculation directly applies the conversion factor to the kpa number to find its equivalent in psi.

Conversion Example

• Convert 150 kpa to psi:
  • Step 1: Write the formula: psi = 150 × 0.145038
  • Step 2: Multiply: 150 × 0.145038 = 21.7557 psi
  • Result: 150 kpa equals approximately 21.7557 psi
• Convert 200 kpa to psi:
  • Step 1: Use formula: psi = 200 × 0.145038
  • Step 2: Multiply: 200 × 0.145038 = 29.0076 psi
  • Result: 200 kpa is roughly 29.0076 psi
• Convert 75 kpa to psi:
  • Step 1: Apply formula: psi = 75 × 0.145038
  • Step 2: Calculate: 75 × 0.145038 = 10.8764 psi
  • Result: 75 kpa converts to about 10.8764 psi
