HOW TO CONVERT PSI to BAR
1 Bar = 14.5037738 Psi
Pressure in Bar = (Pressure in PSI) / 14.5037738
The bar is a metric unit of pressure, but is not part of the SI System of Units. It is defined as exactly equal to 100,000 Pa.
One bar is slightly less than the current average atmospheric pressure on Earth at sea level.
PSI or Pounds per Square Inch is defined as the pressure as a result of applying a one pound-force on a square inch of area.
