Conversion result: 90 kpa equals approximately 13.05 psi.
To convert 90 kilopascals (kpa) to pounds per square inch (psi), multiply the kpa value by 0.145038. This conversion works because 1 kpa is defined as 0.145038 psi. So, multiplying 90 by 0.145038 gives the pressure in psi, providing a quick way to switch between these units.
What is the Conversion from kpa to psi
The conversion from kpa to psi is based on the fact that 1 kilopascal equals 0.145038 pounds per square inch. To convert, you take the value in kpa and multiply it by this factor. This works because both units measure pressure but are used in different measurement systems, with kpa in metric and psi in imperial.

Conversion Formula
The formula to convert kpa to psi is straightforward: psi = kpa * 0.145038. This works because the definition of pressure units relates 1 kpa directly to 0.145038 psi. By multiplying the number of kilopascals by this factor, you convert it into pounds per square inch, which is common in the US.
For example, if you have 100 kpa, multiplying 100 by 0.145038 gives 14.5038 psi. This step-by-step math applies the conversion factor directly, ensuring accurate results for any pressure measurement in kpa you need to convert.
Conversion Example
- Convert 50 kpa to psi:
- Multiply 50 by 0.145038
- 50 * 0.145038 = 7.2519 psi
- Convert 120 kpa to psi:
- Multiply 120 by 0.145038
- 120 * 0.145038 = 17.4046 psi
- Convert 200 kpa to psi:
- Multiply 200 by 0.145038
- 200 * 0.145038 = 29.0076 psi

Conversion Definitions
kpa
Kilopascal (kpa) is a metric pressure unit, equal to 1,000 pascals, measuring force per unit area, mainly used in science and engineering to denote pressure, stress, or load. It is part of the SI system, standard in many countries for pressure measurements.
psi
Pounds per square inch (psi) is an imperial pressure unit, representing force in pounds applied over an area of one square inch. It is commonly used in the US for measuring tire pressure, hydraulic systems, and other pressure-related applications.
Conversion FAQs
How accurate is the conversion from kpa to psi?
The conversion from kpa to psi is precise because it uses a fixed ratio of 0.145038. As long as the multiplication is done correctly, the result is reliable for most engineering and scientific purposes where pressure measurements are needed.
Can I use this conversion for gases at different temperatures?
This conversion assumes standard conditions and does not account for temperature or gas-specific properties. For gases under varying temperatures, pressure may need to be adjusted based on gas laws, but the conversion factor between kpa and psi remains the same.
Is there a simple way to memorize the conversion factor?
One quick way is to remember that 1 kpa roughly equals 0.145 psi. Alternatively, think of 10 kpa as about 1.45 psi, which makes mental calculations easier without memorizing the full decimal.
