Frequently asked questions
What is the source unit in this conversion?
The source unit is the atmosphere (atm). A standard atmosphere is exactly 101,325 pascals.
What is the destination unit in this conversion?
The destination unit is the psi (psi). Pounds per square inch.
How do I convert atmosphere to psi?
Multiply the atmosphere value by 14.695949. For example, 10 atm × 14.695949 = 146.959488 psi.
Is the atmosphere to psi 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 atmosphere needs to be compared with, or reported in, psi, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert psi back to atmosphere?
Yes. Multiply the psi value by 0.068046 to get atmosphere.

About this conversion
This page converts atmosphere (atm) to psi (psi) within the pressure converter.
A standard atmosphere is exactly 101,325 pascals. Pounds per square inch.
The formula is psi = atmosphere × 14.695949, 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.
