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

The units
Exactly 100,000 Pa — very close to atmospheric pressure at sea level.
Used for: Tyre pressure in Europe and India, scuba, espresso machines.
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.
