Various units are used to express pressure. 

Calculating pressure
  1. To calculate pressure, you need to know two things:
  2. Pressure is calculated using this equation:
  3. pressure = force ÷ area.

The basic unit of pressure is the pascal, defined as the pressure exerted by a force of one newton perpendicularly upon an area of one square metre. In North America, however, the US Customary System is preferred. This is based on Imperial units such as the pound (lb) and inch (in) or foot (ft).
