kPa to psi – convert kilopascals to pounds per square inch
Convert kilopascals to pounds per square inch (kPa to psi) to read gauges, manuals and tyre labels from different regions. This page opens the main pressure converter with kPa → psi pre-selected.

Use main converter (kPa → psi) or switch to psi → kPaThe homepage pressure section lets you convert between kPa, psi, bar, atmospheres, millibar, mmHg and more in a single place.
Quick reference: kPa to psi
From the exact factor 1 psi = 6.894757 kPa, we get 1 kPa ≈ 0.145038 psi. Some useful values:
| Pressure (kPa) | Pressure (psi, approx.) |
|---|---|
| 100 kPa | 14.5 psi |
| 150 kPa | 21.8 psi |
| 200 kPa | 29.0 psi |
| 220 kPa | 31.9 psi |
| 240 kPa | 34.8 psi |
| 250 kPa | 36.3 psi |
Why convert kPa to psi?
Typical reasons include:
- Adjusting tyre pressures when the car handbook uses kPa but pumps show psi.
- Comparing engineering or hydraulic specs written for different markets.
- Interpreting HVAC and refrigeration documentation that mixes both units.
- Learning SI units but still seeing imperial pressure units in older material.

Behind the scenes the pressure converter uses pascal (Pa) as its base unit, so all these units line up correctly with each other.
