Large numbers are automatically formatted with thousand separators.
Switch units anytime using the searchable dropdown menus.

kPa to psi Formula

The conversion uses a single fixed factor. To go from Kilopascal to Pound per Square Inch, multiply by the factor below:

psi = kPa × 0.145038

To convert back the other way:

kPa = psi × 6.8948

Example: 1 kPa = 0.145038 psi. Reverse: 1 psi = 6.8948 kPa.
