0.002936 psi
Converting 2 kilopascals (kpa) to pounds per square inch (psi) results in approximately 0.002936 psi. This conversion helps to translate pressure measurements from the metric system to the imperial system, which is often used in the United States for various engineering and industrial applications.
Conversion from kpa to psi
The conversion from kilopascals to pounds per square inch is based on the fact that 1 kpa equals approximately 0.145038 psi. To convert any value from kpa to psi, multiply the number of kilopascals by this factor. This conversion works because both units measure pressure but in different systems, and the factor is derived from their fundamental definitions.

Conversion Formula
The formula to convert kpa to psi is straightforward: multiply the pressure value in kpa by 0.145038. This works because 1 kpa equals 0.145038 psi, a value derived from the definition of the units. For example, converting 10 kpa involves: 10 * 0.145038 = 1.45038 psi.
Conversion Example
- Convert 5 kpa to psi:
- Multiply 5 by 0.145038.
- 5 * 0.145038 = 0.72519 psi.
- So, 5 kpa equals approximately 0.7252 psi.
- Convert 10 kpa to psi:
- Multiply 10 by 0.145038.
- 10 * 0.145038 = 1.45038 psi.
- Thus, 10 kpa equals about 1.4504 psi.
- Convert 15 kpa to psi:
- 15 * 0.145038 = 2.17557 psi.
- Therefore, 15 kpa is approximately 2.1756 psi.
- Convert 20 kpa to psi:
- 20 * 0.145038 = 2.90076 psi.
- So, 20 kpa equals roughly 2.9008 psi.
- Convert 25 kpa to psi:
- 25 * 0.145038 = 3.62595 psi.
- Thus, 25 kpa is about 3.626 psi.

Conversion Definitions
kpa
Kilopascal (kpa) is a metric unit measuring pressure, where 1 kpa equals 1,000 pascals. It is used in scientific, engineering, and industrial contexts to quantify force per unit area, especially in pressure systems and fluid dynamics.
psi
Pounds per square inch (psi) is an imperial pressure unit measuring force applied over an area of one square inch, commonly used in the United States for tire pressures, hydraulics, and other pressure-related measurements in various industries.
Conversion FAQs
Why is the conversion factor between kpa and psi 0.145038?
This factor arises from the relationship between the pascal and the pound per square inch. Since 1 pascal equals approximately 0.000145038 psi, multiplying kpa (which is 1,000 pascals) by 0.145038 converts it directly to psi, reflecting their fundamental definitions.
Can I convert kpa to psi without online tools?
Yes, by using the conversion factor 0.145038, multiply the kpa value directly to get psi. For example, 2 kpa times 0.145038 equals approximately 0.290076 psi. This simple multiplication allows manual conversions without the need for calculators or online tools.
Are the units kpa and psi interchangeable in any applications?
They are not interchangeable because they are part of different measurement systems. However, in specific contexts like engineering calculations, conversions are necessary to switch between metric and imperial measurements, but the units themselves are not interchangeable.
How precise is the conversion from kpa to psi?
The conversion uses a fixed factor (0.145038), so it gives a very accurate result within typical measurement tolerances. Small rounding differences can occur when using limited decimal places, but for most practical purposes, the accuracy is sufficient.
