How to convert bar to psi
Bar and PSI (pounds per square inch) measure pressure in metric and imperial systems. One bar equals approximately 14.5038 PSI. Bar is common in European industrial and meteorological contexts; PSI dominates in US automotive and engineering.
Multiply bar by 14.5038 to get PSI. Formula: psi = bar × 14.5038. 1 bar = 14.5 PSI. 2.5 bar (typical turbo boost) = 36.3 PSI. Atmospheric pressure at sea level ≈ 1.013 bar = 14.7 PSI.
Tire inflation (often 2.0–2.5 bar in Europe, 30–36 PSI in US), pressure washer specs, and scuba tank ratings use this conversion.
Quick values: 1 bar ≈ 14.5 psi, 2 bar ≈ 29 psi, 3 bar ≈ 43.5 psi.
