Frequently asked questions
What is the source unit in this conversion?
The source unit is the centipascal (cPa). Centipascal is 0.010000000000000000208166817117 pascal units.
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 centipascal to atmosphere?
Multiply the centipascal value by 9.869233e-08. For example, 10 cPa × 9.869233e-08 = 9.869233e-07 atm.
Is the centipascal 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 centipascal 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 centipascal?
Yes. Multiply the atmosphere value by 1.013250e+07 to get centipascal.

About this conversion
This page converts centipascal (cPa) to atmosphere (atm) within the pressure converter.
Centipascal is 0.010000000000000000208166817117 pascal units. A standard atmosphere is exactly 101,325 pascals.
The formula is atmosphere = centipascal × 9.869233e-08, 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.
Use the calculator above for instant results, or the table below for common centipascal values already converted to atmosphere.
