Pressure is the forces exerted by particles as they bang around each other and into other things.
In physics, the simple formula for pressure is P = F/A. Or in plain words, Pressure is equal to Force per unit Area.
S.I Unit : Pascal
C.G.S Unit: Dyne/cm^2
Derivation :
Pressure = Force / Area
Units of Pressure = Newton / metre^2 ( Pascal)
C.G.S unit = Dyne/centimetre^2
Also,you may have come across atm, torr and bar.
I'll give you a short conversion of units from “Pa” to atm, torr and bar :
1 atm = 101325 Pa = 760 torr ≈760 mm Hg
1 bar = 105 N/m^2 = 750.06 torr = 0.987 atm.

Answer:
Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). Unit of pressure is Pascals (Pa). ... While you sip the beverage, you're actually applying 'Pressure'.
