Pressure Converter

Convert pressure between pascals, kilopascals, bar, PSI, atmospheres, Torr and related units.

This legacy converter sends only the numeric value and selected units to UsefulUtilities for calculation. The local-first workbench tools are labelled separately.

Calculating…

Assumption: Some mercury-column units depend on conventional density and gravity definitions. Medical, aviation and engineering work may require a specific standard and reference condition.

How it is calculated

Values are converted through pascals. One standard atmosphere is exactly 101,325 Pa; one bar is exactly 100,000 Pa.

Displayed results may be rounded. Verify safety-critical, regulated or high-precision work against the applicable standard and the precision required by your application.
