Unit Definitions
Kilopascal (kPa)
Metric pressure unit (1,000 Pa).
1 kPa = 0.145038 psi; 1 kPa = 0.01 bar; 1 kPa = 10 mbar.
Pound per Square Inch (psi)
Imperial pressure unit used widely in North America.
psi to kPa multiply by 6.89476; psi to bar multiply by 0.0689476; psi to Pa multiply by 6,894.76.
Common Use Cases
- Tire pressure kPa → PSI.
- HVAC and compressor specs.
- Hydraulic test reports.
- Automotive service manuals.
Understanding the Conversion
1 kPa ≈ 0.145038 PSI. Multiply kPa by 0.145038.
Examples: 100 kPa ≈ 14.5 PSI · 200 kPa ≈ 29 PSI · 689 kPa ≈ 100 PSI.
When metric tire or equipment labels use kPa but US gauges use PSI.
Tire pressure kPa → PSI. The table and FAQ on this page walk through the factor if you need it.
