FAQ

Standard atmospheric pressure is defined as 101,325 Pa (1 atm), which equals 14.696 psi, 1.01325 bar, or 760 mmHg at sea level.
PSI (pounds per square inch) is widely used in the US for tire pressure, hydraulics, and industrial applications. Standard tire pressure for cars is typically 30-35 psi.

Quick Tip

1 bar is very close to 1 atm (within 1.3%). In many practical applications, they can be used interchangeably.
