Definition of Pascal



According to the International System of Units, the quantities like pressure and stress are measured in terms of Pascal which is denoted as Pa. This unit was named after the physicist, Blaise Pascal. It can be defined as the pressure of 1 newton exerted on a 1-meter square. In the context of base units of SI, it is stated as the pressure of 1 kilogram per meter per square second.

 


However, the bigger unit of pascal i.e., the kilopascal is more widely used. One standard atmospheric pressure (1 atm) is equal to 101.325 kilopascals. Moreover, one millibar is equal to 100 pascals and this unit is often used in meteorology.
