The bar (bar) is a metric unit of pressure not part of the SI.

The unit is most prominently used in meteorology to express atmospheric air pressure with values generally in millibars.

One bar is roughly equal to the average atmospheric pressure at sea level on Earth.

Definition of the bar

One bar is equal to 100000 pascals.

The pound per square inch (psi, lbf/in²) or psi is a unit of pressure.

The "pound" in "pound per square inch" is the pound-force, not to be confused with the pound the unit of mass. One pound-force is the force exerted downward by a mass of one avoirdupoids pound on the surface of the Earth.

Definition of the pound per square inch

One psi is equal to the pressure exerted by a force of one pound-force on a surface of one square inch.
