Real-world pressure in psi and bar
| Example | PSI | Bar |
|---|---|---|
| A systolic blood pressure of 120 mmHg | 2.320415 psi | 0.159987 bar |
| A pressure cooker's over-pressure (15 psi) | 15 psi | 1.034214 bar |
| The standard atmosphere | 14.69595 psi | 1.01325 bar |
| A typical car tyre (32 psi) | 32 psi | 2.206322 bar |
| An espresso machine (9 bar) | 130.534 psi | 9 bar |
| A road-bike tyre (90 psi) | 90 psi | 6.205282 bar |
| A scuba cylinder (200 bar) | 2,900.755 psi | 200 bar |

The units
Pounds-force per square inch, about 6,894.757 Pa.
Used for: US tyre pressure, air compressors and hydraulics.
Exactly 100,000 Pa — very close to atmospheric pressure at sea level.
Used for: Tyre pressure in Europe and India, scuba, espresso machines.
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.
