What is one bar in PSI?

One bar is equivalent to 14.50 PSI. PSI stands for pounds per square inch and is a common pressure metric in North America.

Bar, PSI and atmospheres are the most commonly used pressure units across most industries. One bar is equal to 14.5 PSI and approximately 0.99 atmospheres.

Pressure is a measure of force over an area. In the case of PSI, it can be measured by recording the amount of pound-force being applied to a certain surface area in square inches. The most common use for pressure measurements in PSI is in material science to determine the tensile strength of different materials.
