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]
The SI unit of pressure is pascal (represented as Pa) which is equal to one newton per square metre (N/m 2 or kg m -1 s -2). Interestingly, this name was given in 1971. Before that pressure in SI was measured in newtons per square metre.

- The pressure is generally started as the amount of force that is exerted on a certain area.
- Pressure is usually represented by the formula p = F/A. Here, ‘F’ is the applied force, and ‘A’ is the area of the region.
- Pascal is the SI unit of pressure.
- One pascal is defined as 1 Newton force applied on an area of 1 m 2 .
- The CGS unit of pressure is barye (Ba). It is equal to 0.1 Pa.
Specifically, a pascal measures the pressure applied by 1 N of force applied on an area of 1 m 2 at a right angle. SI accepted it as the standard unit of pressure in 1971 and named it after Blaise Pascal.
A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared. This unit is inconveniently small for many purposes, and the kilopascal (kPa) of 1,000 newtons per square metre is more commonly used.

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.
The pascal, symbol Pa, is the SI coherent derived unit of pressure. It is the special name for the kilogram per metre per second squared, symbol kg m −1 s −2. One pascal is defined as the pressure exerted by a perpendicular force of one newton on an area of one square metre. Definition. h c−3 Δ νCs4.
Jul 3, 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.
