How to convert kilopascals to pounds per square inch
Translate pressure readings while keeping the same pressure reference.
Formula coefficients shown rounded. Calculations use the stored factors before display rounding.
A worked example
For 10 kPa, the result is approximately 1.450377377 psi. To go the other way, edit the result above or swap the units.
These are pressure units only. Gauge and absolute readings need a reference pressure and are not interchangeable.
Where the numbers come from
Factors follow NIST conversion references and documented unit definitions. Read our accuracy and rounding notes.
