Kilopascals to PSI Converter (kPa to psi)

How to use this calculator: kpa to psi

1. 1Enter the value measured in kilopascal (kPa).
2. 2Confirm the direction is Kilopascal (kPa) to PSI (psi); reversing the units changes the factor or offset.
3. 3Apply psi = kPa × 0.14503768. The live converter performs this substitution as you type.
4. 4Read the answer in psi and keep only justified precision.

Conversion formula

Kilopascals (kPa) are the SI pressure unit shown on tyre placards and gauges in metric countries. One psi equals 6.89476 kPa, so divide kPa by 6.89476 to get psi.

The units measure the same quantity at different scales: 1 kPa = 0.14503768 psi, and 1 psi = 6.89476 kPa.

Worked conversion example: Kilopascals to PSI

1. Given: 150 kPa
2. Substitute: psi = 150 × 0.14503768 = 21.75565212
3. Result: 150 kPa = 21.75565212 psi

Accuracy checklist

The converter keeps extra precision internally. Report only the precision supported by the original measurement and follow the required rounding rule.

Direction check: a smaller unit usually gives a larger number; temperature is an exception.
