The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI). It is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m 2 ). [1]

Pascal Unit – Definition. One Pascal (Pa) is defined as the pressure imparted by a Force of one Newton perpendicularly on the area of one square meter. Mathematically, one can derive the expression as follows, Pressure P = Force F acting perpendicularly per unit area. = Force F / Area A = 1 Newton/1 square metre.
The pascal (symbol: Pa) is the SI -derived unit of pressure or stress. It is a measure of perpendicular force per unit area and is equal to one newton per square meter. In everyday life, the pascal is best known from meteorological air-pressure reports, where it happens in the form of hectopascal (1 hPa = 100 Pa). [1]
What is a pascal? The pascal (Pa) is the unit of pressure or stress in the International System of Units . 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 (m 2).
Apr 25, 2024 · Pascal is the SI Unit of pressure, representing one newton of force applied per square meter of surface area. It’s named after the French mathematician and physicist Blaise Pascal and is widely used in scientific and engineering contexts to measure pressure in fluid systems, material testing, and atmospheric studies.
May 22, 2019 · Pascal is the SI unit of pressure, defined as one newton per square metre. Learn how to convert pascal to other units, such as kPa, bar, MPa, atm, psi, and torr, and the difference between absolute and gauge pressure.
