Is atm to bar the same as bar to atm?
No. They are inverse operations. For this page, 1 atm equals 1.01325 bar, while 1 bar equals 0.9869232667 atm.
Pressure
Convert Standard atmosphere (atm) to Bar (bar) instantly.
Formula
value × 1.01325
| Sample | Converted |
|---|---|
| 1 atm | 1.01325 bar |
| 5 atm | 5.06625 bar |
| 10 atm | 10.1325 bar |
| 100 atm | 101.325 bar |
| 1,000 atm | 1,013.25 bar |
This conversion scales values from a larger pressure unit to a smaller one. That usually increases the numeric value when going from atm to bar.
