1 bar is equal to 1000 millibars. Just like how there are 1000 millilitres in a litre, and 1000 milliseconds in a second. 1 millibar = 0.001 bars.
âlbf/inÂ²â is one of the many acronyms used for âPounds Force per Square Inchâ pressure units of which âpsiâ is the most commonly used. The factor for converting lbf/inÂ² into bar is 0.068948., e.g. 15 psi = 1.03422 bar. psi to bar. What is the equation for psi to bar? psi to bar = multiply by 0.0689476â¦ psi to bar
