VideosPressure Conversion Tables: psi to bar (mbar)
The fluid transfer community uses both, the metric system (international System of Units) as well as the English system (U.S customary system) for pressure data. For your convenience we provide easy pressure conversion tables between psi (pounds per square inch) and bar (mbar) and from bar (mbar) to psi. For more exact data, please use the conversion factors:
1psi = 68.9476 mbar 1bar = 14.5038 psi
You can find high- and low pressure fittings, tubing and connectors in our online shop.
