# Definition

Pressure In physics, pressure is a measure of the force per unit area applied to the surface of an object. The SI unit of pressure is the pascal (Pa) or Newton per square meter (N/m²). Pressure (P) on a surface is defined as the force (F) divided by the surface's area (A): P=F/A. When you type on a computer keyboard, the pressure on a key is equal to the force of your finger exerted on the key divided by the area of your fingertip.

Pressure is also often expressed as a depth of a particular fluid in a manometer such as mercury or water (e.g., millimeter of mercury or centimeter of water). For example, blood pressure is measured in millimeter of mercury.
