Conversion Formula
bar = PSI × 0.068948 PSI = bar × 14.5038 1 PSI = 0.068948 bar 1 bar = 14.5038 PSI Quick estimate: divide PSI by 14.5 ≈ bar Reference conversions: 30 PSI = 2.07 bar (low end car tire) 32 PSI = 2.21 bar (common car tire pressure) 35 PSI = 2.41 bar (SUV tire pressure) 40 PSI = 2.76 bar (performance / light truck) 100 PSI = 6.89 bar (workshop air compressor minimum) 150 PSI = 10.34 bar (standard pneumatic tool supply) 3,000 PSI = 206.8 bar (scuba tank fill pressure)
Frequently Asked Questions
How many bar is 30 PSI?
30 PSI × 0.068948 = 2.07 bar. When an American gauge shows 30 PSI, that is just over 2 bar — the pressure often labeled on European tire gauges for the minimum inflation level.
How many bar is 100 PSI?
100 PSI × 0.068948 = 6.89 bar. A workshop air compressor typically outputs 100–150 PSI (6.9–10.3 bar) for power tools and air inflation.
What is atmospheric pressure in PSI and bar?
Standard atmospheric pressure (1 atm) = 14.696 PSI = 1.01325 bar. Bar is close to but not equal to 1 atm: 1 bar = 0.986923 atm = 14.504 PSI. The difference is less than 1.5%.
How many PSI is a car tire in bar?
A typical 32 PSI car tire = 2.21 bar. A 35 PSI tire = 2.41 bar. For a quick conversion, remember: 2 bar ≈ 29 PSI, 2.5 bar ≈ 36 PSI — useful when reading European tire pressure recommendations.
What pressure is used in hydraulic presses?
Industrial hydraulic presses operate at 1,000–10,000 PSI (69–690 bar) depending on application. Automotive hydraulic jacks operate at 1,500–3,000 PSI (103–207 bar). High-pressure water jet cutting uses up to 60,000 PSI (4,137 bar).
