Pressure conversion
PSI to Kilopascals Converter Guide
Technicians outside the US often need PSI readings expressed in kilopascals for manuals and regulatory paperwork. This page covers the conversion and safety ranges.
Conversion constant
1 PSI = 6.89476 kilopascals
Multiply PSI by 6.89476 to get kPa.
Step-by-step instructions
- 1
Switch the converter to the Pressure category.
- 2
Set PSI (pounds per square inch) as the source unit and Kilopascals as the destination.
- 3
Input the PSI reading from your gauge to see the equivalent kPa.
- 4
Use the quick conversions list for common tire and HVAC pressures.
Conversion formula
kPa = psi × 6.89476
The pascal equals one newton per square meter. Because 1 psi equals 6,894.757 Pa, dividing by 1,000 produces kilopascals.
For tire checks, 32 psi is about 220.6 kPa. Multiply psi by 7 for a quick ballpark.
When people use this conversion
Automotive service
Canadian manuals list tire pressures in kPa. A sticker showing 240 kPa should read about 34.8 psi.
HVAC systems
Technicians balancing refrigerant lines often convert 120 psi suction pressure to ~827 kPa.
Quick reference table
| PSI | Kilopascals | Context |
|---|---|---|
| 15 psi | 103.42 kPa | Scuba tank near empty |
| 32 psi | 220.63 kPa | Passenger vehicle tire |

Frequently asked questions
Are kPa and bar related?
Yes. 1 bar equals 100 kPa. Divide kPa by 100 to get bar, or multiply psi by 0.06895.
How precise do I need to be?
Safety-critical systems should keep four decimal places during calculations, even if gauges display whole numbers.
