Let a body of mass $m \setminus k g$ be resting on a horizontal surface. Let the area of contact be $= A \setminus {m}^{2}$.

Force exerted on the surface by the body$= m g \setminus N$
where $g = 9.81 \setminus m {s}^{-} 2$ is acceleration due to gravity.

Pressure is defined as Force per unit area.
$\therefore$ Pressure is given as $P = \frac{m g}{A} \setminus P a s c a l$
