PSI to kPa formula and what each symbol means
kPa = psi × 6.894757
| Symbol | Meaning |
|---|---|
| psi | Pound per square inch |
| kPa | Kilopascal |
PSI to kPa examples
1 psi
1 psi × 6.894757 = 6.894757 kPa.
10 psi
10 psi × 6.894757 = 68.94757 kPa.
100 psi
100 psi × 6.894757 = 689.4757 kPa.
PSI compared with kPa
One psi is 6.895 times as large as one kPa, so your number gets bigger when you convert PSI to kPa and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About PSI and kPa
Pound per square inch (psi): One pound-force per square inch, about 6,894.757 pascals. Kilopascal (kPa): 1,000 pascals.
Where PSI to kPa conversions are used
Weather maps use hectopascals or millibars, and altitude and diving use bar or atmospheres. Hydraulics, boilers and pneumatic tools list their limits in bar, psi or MPa.
How to calculate PSI to kPa step by step
- Enter the value in psi (the starting unit).
- Multiply by 6.894757, because 1 psi = 6.894757 kPa.
- The product is the value in kPa. To go back, divide by 6.894757 or multiply by 0.1450377.
