If $P$, $F$ and $A$ represent pressure, force and area respectively, then

By scientific definition, pressure ($P$) is defined as the perpendicular thrust or force ($F$) acting per unit surface area ($A$) of a body.The mathematical formula representing this relationship is:
$$\text{Pressure}=\frac{\text{Force}}{\text{Area}}⟹P=\frac{F}{A}$$
