1. Convert 1 psi to the Pa base: 1 × 6,894.75729317 = 6,894.75729317 Pa.
2. Convert from Pa to bar: 6,894.75729317 ÷ 100,000 = 0.068948 bar.
3. Direct factor check: 1 × 0.06894757 = 0.068948 bar.

Unit conversion does not change a gauge reading into absolute pressure or vice versa. Gauge/absolute conversion also needs the applicable ambient pressure.
