Pressure Conversion Calculator

Use our pressure conversion chart and calculator to quickly convert between common pressure units used across industrial, engineering and process applications. Whether you need to convert bar to PSI, PSI to bar, kPa to bar, MPa to bar or compare other pressure ratings, our easy-to-use conversion tool provides a convenient reference.

Pressure can be expressed using a variety of units depending on the application, equipment and country of manufacture. Our pressure conversion chart makes it easier to compare values across commonly used units including bar, PSI (lb/in²), kPa, MPa and kg/cm².

This tool is particularly useful when selecting or specifying industrial equipment such as safety valves, pressure relief valves, pressure reducing valves, pressure gauges and other pressure-related equipment, where understanding and comparing pressure ratings is essential.

Simply find the pressure value you need to convert and use the chart to identify the equivalent pressure in your required unit.
