Frequently asked questions
What is the source unit in this conversion?
The source unit is the PSI (psi). Pounds per square inch.
What is the destination unit in this conversion?
The destination unit is the Atmosphere (atm). A standard atmosphere is exactly 101,325 pascals.
How do I convert PSI to Atmosphere?
Multiply the PSI value by 0.068046. For example, 10 psi × 0.068046 = 0.68046 atm.
Is the PSI to Atmosphere conversion exact?
Yes. Both units belong to the same engineering measurement family (pressure and mechanical stress), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in PSI needs to be compared with, or reported in, Atmosphere, such as in engineering, scientific, or industrial calculations.
Can I convert Atmosphere back to PSI?
Yes. Multiply the Atmosphere value by 14.6959 to get PSI.

About this conversion
This page converts PSI (psi) to Atmosphere (atm) within the engineering converter.
Pounds per square inch. A standard atmosphere is exactly 101,325 pascals.
The formula is atm = psi × 0.068046, based on each unit's fixed relationship to the pressure and mechanical stress base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
