This page opens the pressure converter with psi (pounds per square inch) as the input and bar as the output — type a value and the result appears instantly. One psi equals 6,894.76 pascals, and one bar is exactly 100,000 Pa, so bar = psi × 0.0689476.
The classic use is tire pressure: US door-jamb placards and gauges read in psi, while pumps and manuals in most of Europe read in bar. Typical car values map neatly — 30 psi is about 2.07 bar, 32 psi is 2.21 bar, 36 psi is 2.48 bar — and a road-bike tire at 100 psi is about 6.9 bar. Compressors, pressure washers and espresso machines mix the two units just as often.
The full tool behind this page also converts pascals, kilopascals, megapascals, atmospheres and millimeters of mercury, entirely in your browser with no upload and no sign-up. Both fields sync live, the swap button flips to bar → psi, and the common-values table lists typical tire pressures.
