Comment utiliser ce calculateur
- Enter a pressure.
- Choose the from and to units.
Formule
The pascal (newton per square meter) is the SI unit; other units are defined in pascals.
1 bar = 100,000 Pa
1 atm = 101,325 Pa = 760 Torr
1 psi = 6,894.757 Pa
1 mmHg ≈ 133.322 Pa
Examples
- Tire pressure 32 psi ≈ 2.21 bar ≈ 220.6 kPa.
- Standard atmosphere = 14.696 psi = 1.01325 bar.
Questions fréquentes
Is tire pressure gauge or absolute?
Tire gauges show gauge pressure (above atmospheric). Convert units the same way, but remember it excludes the ~1 bar of air pressure.
What's the difference between mmHg and Torr?
They are almost identical: 1 Torr = 1/760 atm, while 1 mmHg ≈ 1.000000142 Torr.
Which unit is used for blood pressure?
Millimeters of mercury (mmHg).
