The key conversions
One psi is about 0.0689 bar (or 6.895 kPa), so a 32 psi tire is about 2.21 bar. One atmosphere is 14.7 psi or 101.325 kPa — normal sea-level air pressure. Blood pressure and barometers often use mmHg.
Where each unit is used
psi on US tire gauges and air compressors; bar and kPa on metric gauges and specs; atm in chemistry; mmHg in weather reports and medicine. Choose the from and to units to see every equivalent.
