psi to Atmosphere

Exact answer: 1 psi = 0.06804596391 atm (exact defined factor)

psi and Atmosphere describe the same quantity from the Pressure family but come from different systems of units. The factor is defined exactly. Pressure appears in tyre data, weather reports, hydraulics, gas cylinders and vacuum technology.

Examples

011 psi = 0.068046 atm

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 psi = 6894.75729317 Pa. Then the value is converted through the base unit Pa into Atmosphere.
