How to convert bar to pounds per square inch
Compare pressure units on equipment specifications. Keep gauge and absolute reference types consistent.
Formula coefficients shown rounded. Calculations use the stored factors before display rounding.
A worked example
For 10 bar, the result is approximately 145.0377377 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.
