Conversion Formula
To convert kpa to psi, the formula is: psi = kpa × 0.145038. This works because 1 kilopascal equals 0.145038 pounds per square inch. The multiplication scales the pressure value from the metric unit to the imperial unit, making it easy to switch between them.
For example, if you have 50 kpa, multiplying 50 by 0.145038 results in 7.2519 psi. The step-by-step math shows how many psi correspond to a given kpa, ensuring accurate conversions for pressure measurements.
Conversion Example
- Convert 10 kpa to psi:
- Multiply 10 by 0.145038
- 10 × 0.145038 = 1.45038 psi
- Convert 45 kpa to psi:
- Multiply 45 by 0.145038
- 45 × 0.145038 = 6.52671 psi
- Convert 55 kpa to psi:
- Multiply 55 by 0.145038
- 55 × 0.145038 = 7.97709 psi
- Convert 25 kpa to psi:
- Multiply 25 by 0.145038
- 25 × 0.145038 = 3.62595 psi

Conversion Definitions
kpa
Kilopascal (kpa) is a metric pressure unit equal to 1,000 pascals, used to measure force per unit area in systems like meteorology, engineering, and physics. It quantifies the pressure exerted on a surface, often in contexts like weather, machinery, and scientific experiments.
psi
Pounds per square inch (psi) is an imperial pressure unit measuring force in pounds applied over one square inch of area. It is common in the United States for tire pressure, fluid systems, and other applications where pressure measurement is critical.
