Converting Bars (bar) to PSI (psi) is a standard pressure conversion used daily in science, engineering, travel, and everyday life. This conversion bridges the metric and imperial systems — one of the most common cross-system unit lookups worldwide.
1 Bars = 14.5038 PSI. Multiply any Bars value by this factor to get PSI.
| Bars | PSI | |
|---|---|---|
| 0.1 bar | → | 1.45038 psi |
| 0.25 bar | → | 3.62595 psi |
| 0.5 bar | → | 7.2519 psi |
| 1 bar | → | 14.5038 psi |
| 2 bar | → | 29.0076 psi |
| 5 bar | → | 72.519 psi |
| 10 bar | → | 145.038 psi |
| 25 bar | → | 362.595 psi |
Used daily for tyre pressure — EU vehicles spec in bar, US vehicles in psi.
Country usage: Bar is used in Europe and most metric countries for tyre pressure and hydraulics. PSI is standard in the US.
Using 1 bar = 15 psi (a 3.4% overestimate). The correct factor is 14.504.
1 standard atmosphere (atm) is defined as 101,325 Pa — the average air pressure at sea level. At the peak of Mount Everest (8,849 m), atmospheric pressure drops to roughly 0.33 atm, making each breath deliver one-third the oxygen.
