atm to Pa Converter - Standard Atmosphere to Pascal
Standard Atmosphere (atm) to Pascal (Pa)
Direct answer
1 atm = 101,325 Pa
Pa = atm × 101,325
Converter
Conversion formula
Pa = atm × 101,325
atm = Pa × 0.000009869233
Example: 10 atm = 10 × 101,325 = 1,013,250 Pa.

Explanation of the Atmosphere to Pascal Conversion Factor
The conversion factor of 101,325 is derived from the defined relationship between the standard atmosphere and the pascal, where 1 atmosphere is exactly equal to 101,325 pascals.
Definition
The standard atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals (Pa). The pascal is the SI derived unit of pressure.
Principle
The conversion is a direct equivalence based on the definition of the standard atmosphere. Multiplying a pressure in atm by 101,325 yields the pressure in Pa, and dividing a pressure in Pa by 101,325 yields the pressure in atm.
Assumptions
- The conversion uses the exact defined equivalence of 1 standard atmosphere to 101,325 pascals.
Cautions
- This conversion is for the defined standard atmosphere, not for other variations like technical or actual atmospheric pressure.
- Ensure the precision of the result matches the requirements of your calculation when using the conversion factor.
