The bar is a unit of pressure defined as 100,000 pascals (Pa), or 100 kilopascals (kPa). It is a metric unit that is commonly used in various scientific and engineering applications, particularly in fields such as meteorology, oceanography, and various engineering disciplines. To give you a sense of scale, 1 bar is roughly equivalent to the atmospheric pressure at sea level on Earth, which is approximately 1.01325 bar.
