There are number of units to measure pressure—perpendicular force applied on an object of per unit area.
Mathematically, it is expressed as,
P= F/A, where p is a pressure, F is normal force and A is the area of the surface on contact.

Just like other quantities, pressure too is expressed in numbers of units. The most common is pascal (pa), which is also a SI unit of pressure. Most units are derived from a unit of force divided by a unit of area. One pascal is one newton per square metre.

On the same lines, other popular unit is pound-force per square inch (psi). It is the conventional unit of pressure in the imperial and US customary systems.

For atmospheric measurement, the unit that is used frequently is the atm, or the torr. Since there are various units of pressure in different regions and fields, the Pressure unit conversions are essential; our site has tabulated all the pressure related units. Just enter your value, which will be converted into the unit you want it in.

Pressure Unit Definition:
Pressure - the amount of force that is applied to an area where the force is distributed. The metric system unit used to describe pressure is the pascal (Pa) which translates to newtons per square meter. The symbol of pressure is p

Pressure formula:

p =F
F - force
A - area
