FAQ
What pressure units are supported?
6 units: pascal (Pa), bar, psi (pound per square inch), atmosphere (atm), torr, and millimeter of mercury (mmHg).
How do I convert psi to bar?
Divide psi by 14.5038. For example, 30 psi = 2.07 bar.
What is standard atmospheric pressure?
1 standard atmosphere (atm) = 101,325 Pa = 1.01325 bar = 14.6959 psi.
What is the difference between torr and mmHg?
Torr and mmHg are nearly identical. 1 torr = 1 mmHg (133.322 Pa) for practical purposes.
What is tire pressure typically measured in?
Tire pressure is commonly measured in psi (US/UK) or bar (Europe). Typical car tire pressure is 30-35 psi (2.1-2.4 bar).
