How to convert Atmospheres to Pascals
To convert atmospheres to pascals, multiply by 101,325. One atmosphere equals 101,325 Pa, and one pascal equals 0.0000098692 atm.
- Take the value in atmospheres — for example 7.5 atm.
- Multiply by 101,325 (the number of pascals in one atmosphere).
- 7.5 × 101,325 = 759,937.5 Pa.

About converting Atmospheres to Pascals
Atmospheres (atm) and Pascals (Pa) are both units of pressure. The exact factor is 1 atm = 101,325 Pa, so multiply by 101,325 to go from atmospheres to pascals (or divide to go back).

Real-world pressure in atmospheres and pascals
| Example | Atmospheres | Pascals |
|---|---|---|
| A systolic blood pressure of 120 mmHg | 0.157895 atm | 15,998.7 Pa |
| A pressure cooker's over-pressure (15 psi) | 1.020689 atm | 103,421.4 Pa |
| The standard atmosphere | 1 atm | 101,325 Pa |
| A typical car tyre (32 psi) | 2.177471 atm | 220,632.2 Pa |
| An espresso machine (9 bar) | 8.882309 atm | 900,000 Pa |
| A road-bike tyre (90 psi) | 6.124137 atm | 620,528.2 Pa |

The units
The standard atmosphere: exactly 101,325 Pa, average sea-level air pressure.
Used for: Chemistry, diving and physics.
The SI unit of pressure: one newton per square metre.
Used for: Science and engineering.
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.
