The conversion of 145 kpa to psi yields approximately 21.03 psi.
Since 1 kilopascal (kpa) equals about 0.145038 psi, multiplying 145 kpa by this factor gives the psi value. This simple calculation helps to translate pressure measurements from the metric system to the imperial system, making it easier to understand in contexts like tire pressure or weather forecasts.

Conversion Formula
The formula to convert kilopascals to pounds per square inch is: psi = kpa × 0.145038. This works because 1 kpa equals about 0.145038 psi, based on their definitions in pressure measurement systems. Multiplying the kpa value by this factor gives the psi equivalent.
For example, if you have 200 kpa, then the calculation is 200 × 0.145038 = 29.0076 psi. The factor 0.145038 is derived from the exact relationship between the two units, ensuring precise conversions in practical applications.
Conversion Example
- Convert 100 kpa to psi:
- Step 1: Write the formula: psi = 100 × 0.145038
- Step 2: Multiply: 100 × 0.145038 = 14.5038 psi
- Result: 100 kpa equals approximately 14.50 psi
- Convert 50 kpa to psi:
- Step 1: Formula: psi = 50 × 0.145038
- Step 2: Multiply: 50 × 0.145038 = 7.2519 psi
- Result: 50 kpa is about 7.25 psi
- Convert 170 kpa to psi:
- Step 1: Formula: psi = 170 × 0.145038
- Step 2: Multiply: 170 × 0.145038 = 24.659 psi
- Result: 170 kpa equals approximately 24.66 psi
