How pressure converter works
Convert common pressure units for technical reference.
Formula and convention
Convert through pascals. One bar = 100,000 Pa; one standard atmosphere = 101,325 Pa.A worked example
One bar is approximately 14.503774 psi.
Scope and precision
This converts units, not gauge pressure to absolute pressure. Keep the reference pressure consistent when comparing measurements.
Displayed results may be rounded. Inputs are processed locally and are not stored by this site. Keep the original values if you need to reproduce the result.
Why might another tool give a different result?
Compare unit definitions, rounding, period assumptions, and input values. This page states the convention used by this calculator.
