Conversion Formula
The formula to convert psi into kpa is simple: multiply the psi value by 6.89476. This works because 1 psi equals exactly 6.89476 kpa, which is derived from the relationship between pounds per square inch and the SI unit of pressure, the kilopascal. For example, 50 psi times 6.89476 gives 344.738 kpa.
Conversion Example
- Convert 50 psi:
- Multiply 50 by 6.89476
- 50 x 6.89476 = 344.738
- Result is 344.738 kpa
- Convert 200 psi:
- Multiply 200 by 6.89476
- 200 x 6.89476 = 1378.952
- Result is 1378.952 kpa
- Convert 75 psi:
- Multiply 75 by 6.89476
- 75 x 6.89476 = 517.107
- Result is 517.107 kpa
- Convert 10 psi:
- Multiply 10 by 6.89476
- 10 x 6.89476 = 68.9476
- Result is 68.9476 kpa

Conversion Definitions
Psi (pounds per square inch) measures pressure based on the force of one pound applied over an area of one square inch. Kilopascal (kpa) is the SI unit for pressure, representing one thousand newtons per square meter, used worldwide in scientific and engineering contexts.
Conversion FAQs
How accurate is converting 120 psi to kpa?
The conversion using the factor 6.89476 is precise for practical purposes. Minor variations may occur due to rounding, but for most engineering and scientific uses, it provides a reliable estimate of pressure in kpa from psi.
Can I convert other pressure units to kpa in this tool?
No, this specific tool is designed only for psi to kpa conversion. To convert other units like bar or atm, separate formulas and tools are necessary.
Why is the conversion factor 6.89476 used?
This factor is derived from the exact definition of psi as pounds per square inch and the SI unit of pressure, the kilopascal, which is Newtons per square meter. It ensures precise conversion between these units.
What should I do if I need to convert a pressure value in psi to kpa manually?
Multiply the psi value by 6.89476. For example, to convert 150 psi, calculate 150 x 6.89476 = 1034.214 kpa.
