psi to kPa Converter
Convert psi to kilopascals for tire pressure, engineering, and scientific measurement.
How It Works
Formula: psi to kPa = value × 6.89475729
Example: 32 psi = 220.632233 kPa
Note: 1 psi equals 6.8948 kilopascals, the conversion from US pressure to the SI unit.
Common Uses
Rounding Rule
Rounded to 2 decimal places
Error Margin
±0.01 kPa
Precision Guidance
For tires, round to whole kPa. For engineering, keep 2 decimals.
Common Mistakes
1 psi is 6.895 kPa, not 6.895 bar. Keep psi, bar, and kPa straight when reading tire labels.
