About this tool
This page opens the pressure converter preset to bar → psi. One bar is exactly 100,000 pascals and one psi is 6,894.76 Pa, so one bar equals about 14.5038 psi — the tool divides by the exact ratio and rounds only for display.
Reference points: 1 bar is 14.5 psi (and very close to 1 atmosphere, 14.7 psi), a car tire at 2.2 bar is 31.9 psi, 2.5 bar is 36.3 psi, and an 8-bar compressor delivers about 116 psi. This direction is what you need when a European pump or manual states bar but your gauge, bike pump or US spec sheet reads psi.
Everything runs locally in your browser: no server calls, no account, and the page keeps working offline once loaded. The full converter also covers Pa, kPa, MPa, atm and mmHg; type in either field for two-way conversion or press swap to go back to psi → bar.
Example. Entering 1 atmosphere returns 101325 pascals, the exact factor stored for that unit.
Limit. The set is pascal, kilopascal, megapascal, bar, psi, atmosphere, and millimeter of mercury, with psi at 6894.76 Pa and mmHg at 133.322 Pa.
