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 Bar (bar). A bar is exactly 100,000 pascals.
How do I convert Atmosphere to Bar?
Multiply the Atmosphere value by 1.01325. For example, 10 atm × 1.01325 = 10.1325 bar.
Is the Atmosphere to Bar conversion exact?
Yes. Both units belong to the same engineering measurement family (pressure and mechanical stress), so the ratio between them is a fixed, defined value 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, Bar, such as in engineering, scientific, or industrial calculations.
Can I convert Bar back to Atmosphere?
Yes. Multiply the Bar value by 0.986923 to get Atmosphere.

About this conversion
This page converts Atmosphere (atm) to Bar (bar) within the engineering converter.
A standard atmosphere is exactly 101,325 pascals. A bar is exactly 100,000 pascals.
The formula is bar = atm × 1.01325, based on each unit's fixed relationship to the pressure and mechanical stress base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
