How to convert Pascals to Atmospheres
To convert pascals to atmospheres, multiply by 0.0000098692. One pascal equals 0.0000098692 atm, and one atmosphere equals 101,325 Pa.
- Take the value in pascals — for example 7.5 Pa.
- Multiply by 0.0000098692 (the number of atmospheres in one pascal).
- 7.5 × 0.0000098692 = 0.0000740192 atm.

About converting Pascals to Atmospheres
Pascals (Pa) and Atmospheres (atm) are both units of pressure. The exact factor is 1 Pa = 0.0000098692 atm, so multiply by 0.0000098692 to go from pascals to atmospheres (or divide to go back).

Real-world pressure in pascals and atmospheres
| Example | Pascals | Atmospheres |
|---|---|---|
| A systolic blood pressure of 120 mmHg | 15,998.7 Pa | 0.157895 atm |

| The standard atmosphere | 101,325 Pa | 1 atm |
| A typical car tyre (32 psi) | 220,632.2 Pa | 2.177471 atm |
| An espresso machine (9 bar) | 900,000 Pa | 8.882309 atm |
| A road-bike tyre (90 psi) | 620,528.2 Pa | 6.124137 atm |

The units
The SI unit of pressure: one newton per square metre.
Used for: Science and engineering.
The standard atmosphere: exactly 101,325 Pa, average sea-level air pressure.
Used for: Chemistry, diving and physics.
The bar (100,000 Pa) and the standard atmosphere (101,325 Pa) are exact; psi is derived from the pound-force and the inch, so its factor is a rounded value of an exact fraction.
