Psi to Kilopascals Converter
How to convert psi to kilopascals
kilopascals = psi × 6.89475729
To convert psi to kilopascals, multiply the number of psi by 6.89475729.
1 psi = 6.89475729 kPa
Examples
- A typical car tire pressure: 32 psi × 6.89475729 = 220.632233 kPa
- 100 psi × 6.89475729 = 689.475729 kPa
Good to know
One psi is about 6.895 kPa, and 100 kPa is about 14.5 psi. Tire placards in many countries show both units.
Psi means pounds-force per square inch (lbf/in²). Gauge readings (psig) are measured relative to atmospheric pressure, absolute readings (psia) relative to a vacuum; the conversion factor is the same for both.

Unit definitions
- Psi
- Psi is one pound-force per square inch, about 6894.757 pascals. It is the everyday pressure unit in the United States, used for tires, compressors and plumbing.
- Kilopascal (kPa)
- A kilopascal is 1000 pascals. It is the common SI unit for tire pressures, weather reports and engineering in metric countries.
