The conversion of 30 kpa to psi results in approximately 4.35 psi.
This is calculated by multiplying 30 kilopascals (kpa) with the conversion factor of 0.145038, which is the amount of psi in one kpa. Therefore, 30 kpa equals 30 × 0.145038 = 4.35114 psi, rounding to two decimal places gives 4.35 psi.
Conversion Result and Explanation
30 kpa equals about 4.35 psi. To convert kilopascals to pounds per square inch, we use the fact that 1 kpa equals approximately 0.145038 psi. Multiplying the kpa value by this factor gives us the psi equivalent, which is a common pressure measurement used in various fields like engineering and weather forecasting.

Conversion Formula
The formula for converting kilopascals to psi involves multiplying the kpa value by the conversion factor 0.145038. This works because 1 kpa equals 0.145038 psi, a fixed ratio derived from the definitions of these pressure units. For example, converting 50 kpa: 50 × 0.145038 = 7.252 psi.
Conversion Example
- Convert 50 kpa to psi:
- Multiply 50 by 0.145038
- 50 × 0.145038 = 7.2519 psi
- Answer is approximately 7.25 psi
- Convert 10 kpa to psi:
- Calculate 10 × 0.145038
- 10 × 0.145038 = 1.45038 psi
- This equals about 1.45 psi
- Convert 100 kpa to psi:
- Multiply 100 by 0.145038
- 100 × 0.145038 = 14.5038 psi
- Resulting in roughly 14.50 psi
- Convert 75 kpa to psi:
- 75 × 0.145038 = 10.8779 psi
- Answer about 10.88 psi

Conversion Definitions
kpa
Kilopascal (kpa) is a pressure unit, where 1 kpa equals 1,000 pascals, measuring force per area. It is commonly used to quantify pressure in engineering, weather, and fluid systems, representing the force exerted over a square meter.
psi
Pounds per square inch (psi) is a pressure measurement indicating force in pounds applied over an area of one square inch. It is used widely in tire pressures, hydraulics, and various industrial applications to express pressure levels.
Conversion FAQs
Why is the conversion factor from kpa to psi 0.145038?
This factor is derived from the relationship between pascals and pounds per square inch, with 1 pascal equal to approximately 0.000145038 psi. Since 1 kpa equals 1,000 pascals, multiplying by this factor gives the psi equivalent for kpa values.
Can I use a calculator to convert any kpa to psi?
Yes, multiplying the kpa value by 0.145038 will give an accurate psi conversion. For quick calculations, a calculator or online converter simplifies the process, especially for larger or more precise values.
Is the conversion from kpa to psi linear?
Yes, pressure conversions between kpa and psi are linear because they are based on a fixed ratio. Doubling the kpa value will double the psi value, following the multiplication by 0.145038.
What other units can I convert from kpa?
Besides psi, kilopascals can be converted to bars, atmospheres, or millimeters of mercury, depending on the measurement needs. Each uses its own conversion factors, but the kpa value remains the starting point.
