Frequently asked questions
What is the source unit in this conversion?
The source unit is the pascal (Pa). The pascal is one newton per square meter.
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 pascal to atmosphere?
Multiply the pascal value by 0.00001. For example, 10 Pa × 0.00001 = 0.000099 atm.
Is the pascal 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 pascal 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 pascal?
Yes. Multiply the atmosphere value by 101325 to get pascal.

About this conversion
This page converts pascal (Pa) to atmosphere (atm) within the pressure converter.
The pascal is one newton per square meter. A standard atmosphere is exactly 101,325 pascals.
The formula is atmosphere = pascal × 0.00001, 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.
