**P= F/A**

**Where,**

P is the pressure,

F is the normal force,

A is the area of the surface area on contact

Or

**Pressure =** Force / Area.

Pressure is the result of a force applied to a surface. Pressure is the amount of force acting per unit area. The symbol of pressure is P. Pressure is a scalar quantity. It relates the vector surface element (a vector normal to the surface) with the normal force acting on it. The SI unit for pressure is the pascal (Pa), equal to one newton per square meter (N/m2 or kg·m−1·s−2).

Pressure (the symbol: P) is the force per unit area applied in a direction perpendicular to the surface of an object. Gauge pressure is the pressure relative to the local atmospheric or ambient pressure.

**Example:**

Convert the 25 atmosphere to barad.

**Solution:**

25 atmosphere = **250 barad**
