0.4348 psi is the result of converting 3 kpa to psi.
This conversion is based on the fact that 1 kilopascal (kpa) equals approximately 0.1450377 pounds per square inch (psi). So, multiplying 3 kpa by this factor gives the equivalent pressure in psi, which helps in understanding pressure measurements across different units.
Conversion Result
3 kpa equals approximately 0.4348 psi.

Conversion Formula
The formula to convert kilopascals (kpa) to pounds per square inch (psi) is: psi = kpa × 0.1450377. This works because pressure units are related through this fixed ratio. For example, to convert 10 kpa: 10 × 0.1450377 = 1.4504 psi.
By multiplying the kpa value by 0.1450377, we directly translate the pressure measurement from kilopascals into psi, which is often used in the United States for pressure systems.
Conversion Example
- Convert 5 kpa to psi:
- Step 1: Write down the value in kpa: 5
- Step 2: Multiply by 0.1450377: 5 × 0.1450377
- Step 3: Calculate: 0.7251885
- Result: 5 kpa equals approximately 0.7252 psi.
- Convert 10 kpa:
- Step 1: Value is 10
- Step 2: Multiply by 0.1450377: 10 × 0.1450377
- Step 3: Result is 1.4504 psi
- Convert 1.5 kpa:
- Step 1: Value is 1.5
- Step 2: Multiply by 0.1450377: 1.5 × 0.1450377
- Step 3: Calculate: 0.21755655
- Result: 1.5 kpa equals approximately 0.2176 psi.

Conversion Definitions
kpa
Kilopascal (kpa) is a metric unit of pressure measuring force per unit area, where 1 kpa equals 1000 pascals. It is used in engineering and science to quantify pressure, with common applications including weather, hydraulics, and material testing.
psi
Pounds per square inch (psi) is a pressure unit that measures force in pounds applied over one square inch of area. Widely used in the United States, it is common in tire pressure, plumbing, and industrial pressure gauges.
Conversion FAQs
Why is 0.1450377 used as the conversion factor from kpa to psi?
This factor comes from the exact relationship where 1 kilopascal equals 0.1450377 pounds per square inch, derived from the definitions of pascals and pounds-force per square inch, ensuring precise pressure conversion between these units.
Can I convert kpa to psi manually for any given value?
Yes, multiply the kpa value by 0.1450377 to get the psi equivalent. For example, for 7 kpa, 7 × 0.1450377 = 1.0153 psi. This straightforward calculation makes conversions quick and accessible without specialized tools.
Is the conversion factor the same for all pressure measurements?
Yes, the ratio 1 kpa = 0.1450377 psi holds universally because both units are defined based on fundamental physical constants. Therefore, the same factor applies regardless of pressure magnitude.
