The pascal is the derived unit of pressure in the international system of units (often abbreviated to SI) that can be used to quantify several parameters such as stress, internal pressure, the Young modulus, and ultimate tensile strength.
The French mathematician, inventor, and physicist Blaise Pascal inspired the SI unit of pressure.
The standard atmosphere (denoted by the symbol 'atm') is another unit of pressure measurement that can be defined as 101325 Pascals.
The Pascal is represented by the symbol 'Pa.' Because pressure is defined as force per unit area, one Pascal is equal to one Newton of force applied over one square meter of area.
