Units of measurement let us describe and compare length, weight, area, volume, density and other values. Units can be imperial or metric and they can be converted using conversion factors.
Pressure is the forceA push or a pull. The unit of force is the newton (N). per unit area.
The pressure exerted by a solid object which is resting on top of another solid surface is the weight of the object divided by the area of the object's surface.
One Pascal is equivalent to one newtonUnit of force named after British scientist Isaac Newton (1642-1727), eg the frictional force on the boat is 20,000 N./m2.
Example
The surface area of a pair of skis is 0.25 m2. The weight of a skier is 700N. How much pressure does the skier exert on the snow?
