How it works
Pressure is force per unit area. All these units express the same thing relative to the SI pascal (one newton per square metre), so conversion is a matter of scaling to and from pascals.
1 PSI = 6894.76 Pa · 1 bar = 100 000 Pa
1 atm = 101 325 Pa = 14.6959 PSI = 760 torr
1 atm = 101 325 Pa = 14.6959 PSI = 760 torr
Worked example
A tyre at 32 PSI equals 32 × 6894.76 = 220 632 Pa, which is about 2.21 bar or 2.18 atm.
