Detailed explanation-1: -The pascal (Pa) is the unit of pressure or stress in the International System of Units (SI). It is named after the scientist and mathematician Blaise Pascal. One pascal is equivalent to 1 newton (N) of force applied over an area of 1 square meter (m2).
Detailed explanation-2: -A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared.
Detailed explanation-3: -Unit of pressure: pascal (Pa) Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2).
Detailed explanation-4: -One pascal can be defined as the pressure exerted on a surface of area 1m2 by a force of 1N that acts normally on it. The S.I unit of pressure is newton per meter2.
