Sir William Napier Shaw introduced usage of the bar as a unit.

The bar is a unit of pressure established as one million dynes per square centimeter (equivalently in SI units, 100 kilopascals, or in CGS units, one megabarye). It is approximately equal to the atmospheric pressure on Earth at mean sea level. Alternatvely, bar is a unit of pressure equal to the pressure of 29.530 inches or 750.062 millimeters of mercury under the standard conditions of 0o C temperature and 9.80665 m/s2 gravitational acceleration.
