Convert bar to pounds per square inch (psi) instantly, using the standard relationship where one bar is about 14.5038 psi. This conversion is handy for tires, pumps, compressors, and diving gear when a pressure is given in bar, common on European equipment, but you need the psi figure used on American gauges. Type any pressure in bar and the psi value appears live as you type, carried to several decimals for accuracy. One bar is defined as exactly 100000 pascals, and this tool derives the psi relationship from the exact pascal definition, so the result is precise. Multiplying by 14.5 by hand loses accuracy, so letting the tool convert keeps you correct, which matters when setting tire or equipment pressures.
