The force exerted on a surface divided by the total area over which it is exerted is called pressure.

Here's the formula:

Pressure (P) = Force (F) / Area (A)

Units:

* Pressure is typically measured in Pascals (Pa) or pounds per square inch (psi).

* Force is measured in Newtons (N) or pounds (lb).

* Area is measured in square meters (m²) or square inches (in²).

Example:

If a force of 100 Newtons is applied to a surface with an area of 5 square meters, the pressure exerted on the surface is:

P = 100 N / 5 m² = 20 Pa
