1 bar equals exactly
100.000 Pa
The bar is a unit of pressure commonly used in meteorology and industrial contexts, while the Pascal (Pa) is the pressure unit of the International System. One bar is exactly equal to 100,000 Pa, a value close to the average atmospheric pressure at sea level.
To convert a measurement from bar to Pascal, simply multiply the value in bar by 100,000:
To convert from Pascal to bar, perform the inverse operation, dividing by 100,000:
The bar is widely used in everyday life to indicate the pressure of tires, boilers, and plumbing systems, because it returns convenient, easy-to-remember numbers. The Pascal, being the official SI unit, is instead the standard in scientific calculations and physics formulas, where dimensional consistency with other system units is required.
