  1. Various units are used to express pressure. Some of these derive from a unit of force divided by a unit of area; the SI unit of pressure, the pascal (Pa), for example, is one newton per square metre (N/m 2); similarly, the pound-force per square inch (psi) is the traditional unit of pressure in the imperial and U.S. customary systems.
    Common symbols: p, P
    Derivations from other quantities: p = F / A
    In SI base units: 1 N/m², 1 kg/(m·s²), or 1 J/m³
    SI unit: pascal [Pa]

    What is the formula for pressure in physics?
    - SI Unit, CGS Unit, MKS Unit The pressure is usually defined as the amount of force that is applied to a certain area. The pressure is a physical quantity and mostly expressed as formula p = F/A where F and A are force per area perpendicular to the surface.
    What is PSI in physics?
    It is defined as a force exerted by one pound-force on the surface of one square inch. The derived units of it are the kilopound per square inch (kpsi) and the megapound per square inch (Mpsi). psi is usually used to measure gauge pressure i.e., pressure relative to atmospheric pressure.
