Examples

010.5 atm = 7.347974 psi

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

bar, psi and atm appear in different fields. Tyre, weather and lab values need context.

03Base unit: Pa

1 atm = 101325 Pa. Then the value is converted through the base unit Pa into psi.
