10 Free Online Bar to PSI Converter Websites

Here is a list of the best free online bar to psi converter websites. Both bar and psi are units of pressure measurement. These units have different origins and applications. Bar falls under the metric unit system where it represents the force exerted by a fluid/gas per unit area. 1 bar is approximately equal to the atmospheric pressure at sea level. On the other hand, Psi (pound per square inch) is under the imperial unit system. 1 psi is equal to the pressure exerted by 1 pound-force of force on one square inch of area. 1 bar is approximately equal to 14.5038 psi.

This post covers 10 free websites where you can convert bar to psi online. These websites feature dedicated bar to psi converters where you can add pressure value in bar and convert that to psi instantly. Most of these converters can perform psi to bar conversion as well and have a conversion table for quick look-up. Let’s go through the post and explore these in detail.
