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 are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions 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 specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert atmosphere back to psi?
Yes. Multiply the atmosphere value by 14.695949 to get psi.

About this conversion
This page converts psi (psi) to atmosphere (atm) within the pressure converter.
Pounds per square inch. A standard atmosphere is exactly 101,325 pascals.
The formula is atmosphere = psi × 0.068046, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
