psi to kPa – convert pounds per square inch to kilopascals
Convert psi to kPa (pounds per square inch to kilopascals) for tyre pressures, hydraulics, refrigeration systems and engineering work. This page links to the main pressure converter with psi → kPa pre-selected.
Open the interactive psi → kPa converter:
Use main converter (psi → kPa) or switch to kPa → psiOn the homepage pressure tab you can also convert bar, atmospheres, millibar, pascal and mmHg using the same engine.
Quick reference: psi to kPa
The converter uses the precise factor 1 psi = 6.894757 kPa. Rounded examples:
| Pressure (psi) | Pressure (kPa, approx.) |
|---|---|
| 10 psi | 68.9 kPa |
| 20 psi | 137.9 kPa |
| 30 psi | 206.8 kPa |
| 32 psi | 220.6 kPa |
| 35 psi | 241.3 kPa |
| 40 psi | 275.8 kPa |
Why convert psi to kPa?
Common use cases include:
- Checking tyre pressures when the car manual and pump use different units.
- Comparing industrial or hydraulic specifications listed in psi vs kPa.
- Working in engineering or HVAC where kPa is the preferred SI unit.
- Interpreting online guides and manuals from different countries.
