Where this conversion is used
Bar and psi measure the same thing in metric and US units. The conversion comes up on tyre gauges, air compressors, pressure washers, hydraulic equipment and gas cylinders, where European data sheets quote bar and American ones quote psi.
Watch the reference: tyre and compressor readings are gauge pressure (psig, bar g), measured above the surrounding air, while vacuum and process data are often absolute (psia, bar abs). The factor is the same either way, as long as both sides use the same reference.
Frequently asked questions
How many psi are in 1 bar?
1 bar = 14.5038 psi. In the other direction, 1 psi = 0.0689476 bar.
How do I convert bar to psi?
Multiply the value in bar by 14.5038. Example: 2.5 bar = 36.259 psi.
What is 2 bar in psi?
2 bar is 29.01 psi. A quick check: bar × 14.5 gives psi to within 0.03 %.
What is the difference between psi, psig and psia?
psig is gauge pressure, measured above local atmospheric pressure; psia is absolute pressure, measured from a perfect vacuum. psia = psig + 14.696 at sea level. Plain "psi" usually means psig on tyres and compressors.
