How to convert Pascals to PSI
To convert pascals to psi, multiply by 0.000145038. One pascal equals 0.000145038 psi, and one psi equals 6,894.757 Pa.
- Take the value in pascals — for example 7.5 Pa.
- Multiply by 0.000145038 (the number of psi in one pascal).
- 7.5 × 0.000145038 = 0.00108778 psi.

Real-world pressure in pascals and psi
| Example | Pascals | PSI |
|---|---|---|
| A systolic blood pressure of 120 mmHg | 15,998.7 Pa | 2.320415 psi |
| A pressure cooker's over-pressure (15 psi) | 103,421.4 Pa | 15 psi |
| The standard atmosphere | 101,325 Pa | 14.69595 psi |
| A typical car tyre (32 psi) | 220,632.2 Pa | 32 psi |
| An espresso machine (9 bar) | 900,000 Pa | 130.534 psi |
| A road-bike tyre (90 psi) | 620,528.2 Pa | 90 psi |

The units
The SI unit of pressure: one newton per square metre.
Used for: Science and engineering.
Pounds-force per square inch, about 6,894.757 Pa.
Used for: US tyre pressure, air compressors and hydraulics.
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.
