Where it is used
Psi is converted to bar when American tyre charts, pump manuals or bicycle suspension instructions give pressure in psi, while your gauge shows bar. For example, 32 psi is 2.21 bar and 35 psi is 2.41 bar.
A quick mental shortcut
1 psi = 0.0689476 bar. Roughly, divide by 14.5: 29 psi / 14.5 = 2 bar. Another rough way is to multiply by 0.07 (the result is about 1.5% too high).
Exact examples: 32 x 0.0689476 = 2.206 bar; 100 psi = 6.895 bar.
Good to know
Psi stands for pounds per square inch, that is pounds-force per square inch. Many gauges show gauge pressure relative to the atmosphere, not absolute pressure.
