Conversion Formula
The formula to convert kilopascal (kpa) to psi is: psi = kpa × 0.145038. This formula works because the conversion factor 0.145038 is the ratio between 1 kpa and psi. For example, if you have 250 kpa, multiply 250 by 0.145038 to get the psi value: 250 × 0.145038 = 36.2595 psi.
Conversion Example
- Let’s convert 100 kpa to psi:
- Step 1: Write down the value in kpa: 100.
- Step 2: Multiply by 0.145038: 100 × 0.145038 = 14.5038 psi.
- Step 3: The result is 14.5038 psi.
- Now convert 500 kpa:
- Step 1: Value in kpa: 500.
- Step 2: Multiply: 500 × 0.145038 = 72.519 psi.
- Result: 72.519 psi.
- Convert 750 kpa:
- Step 1: 750 kpa.
- Step 2: 750 × 0.145038 = 108.7785 psi.
- Result: 108.7785 psi.
- Finally, convert 125 kpa:
- Step 1: 125 kpa.
- Step 2: 125 × 0.145038 = 18.12975 psi.
- Result: 18.12975 psi.
