The conversion of 25 kpa to psi equals approximately 3.63 psi.
To convert kilopascal (kpa) to pounds per square inch (psi), multiply the kpa value by 0.1450377. Since 1 kpa equals 0.1450377 psi, applying this factor gives the result. For example, 25 kpa times 0.1450377 results in about 3.63 psi.
Conversion Result and Explanation
25 kilopascals converts to roughly 3.63 pounds per square inch. This conversion is based on the fixed relationship between the two units, where 1 kpa equals 0.1450377 psi. Using this ratio ensures accurate and consistent conversion across different pressure measurements.

Conversion Formula
The formula to convert kpa to psi is: psi = kpa × 0.1450377. This works because 1 kilopascal equals 0.1450377 pounds per square inch. By multiplying the pressure value in kpa by this factor, we directly translate it into psi, maintaining the proportional relationship.
For example, if you have 50 kpa, multiply 50 by 0.1450377: 50 × 0.1450377 = 7.251885 psi. This linear relationship makes conversions simple, as it directly scales the pressure value from kpa to psi based on the fixed conversion factor.
Conversion Example
- Convert 10 kpa to psi:
- Multiply 10 by 0.1450377
- 10 × 0.1450377 = 1.4504 psi
- Convert 50 kpa to psi:
- 50 × 0.1450377 = 7.251885 psi
- Convert 100 kpa to psi:
- 100 × 0.1450377 = 14.50377 psi
- Convert 75 kpa to psi:
- 75 × 0.1450377 = 10.8778 psi
- Convert 5 kpa to psi:
- 5 × 0.1450377 = 0.7252 psi

Conversion Definitions
kpa
Kilopascal (kpa) is a metric pressure unit equal to 1,000 pascals, measuring force per unit area. It is used in scientific and engineering contexts to express pressure levels, and is part of the SI system, with 1 kpa roughly equivalent to 0.145 psi.
psi
Pounds per square inch (psi) is an imperial pressure unit expressing force in pounds applied over an area of one square inch. It commonly measures tire pressures, hydraulics, and other pressure-related fields in the US customary system.
Conversion FAQs
Why is the conversion factor 0.1450377 used for kpa to psi?
This factor is derived from the exact relationship between the pascal and the pound per square inch, where 1 pascal equals approximately 0.0001450377 psi. Multiplying kpa values by this factor converts the metric measurement into the imperial system precisely.
Can I convert kpa to psi without a calculator?
Yes, by memorizing or approximating the conversion factor of about 0.145, you can estimate psi values from kpa. For example, multiplying by 0.14 gives a close estimate, but for precise calculations, using the exact factor or a calculator is recommended.
What is the significance of converting pressure units?
Converting between pressure units like kpa and psi allows for better understanding and communication of pressure measurements across different systems, ensuring compatibility in engineering, safety standards, and scientific research.
