Frequently Asked Questions
What does PSI stand for?
PSI stands for Pounds per Square Inch, which is the standard imperial unit for pressure used primarily in the United States.
Why do mechanics use Bar instead of PSI in Europe?
Bar is a metric unit of pressure that is roughly equal to atmospheric pressure at sea level, making it a highly convenient and standard measurement for tires and hydraulics across Europe.
How do I convert Torr to Atmospheres?
One standard atmosphere (atm) is exactly equal to 760 Torr.
