How is the pressure measured?

The term "pressure" refers toa physical quantity characterized by the state of a continuous surface. According to the numerical equivalent, the pressure is equal to the force that affects the unit of the surface, being perpendicular to it. In the simplest situation, the pressure determines the ratio of a given force and some element of a surface with an area.

So, in what is the pressure measured? Units of pressure measurement are considered to be the following values: millimeter and micron of mercury or water column, expressed in torrals and torrents 10-3; bar; atmosphere (technical and physical); kilogram-force per one square cm. or sq. m .; din or barium per one square cm. pound-force per one square. inch of the pjaz, expressed by one ton-force or one wall per one square meter;

The most common unit isPascal - the ratio of 1 Newton per 1 sq. M. Pressure indicators can be measured with the help of devices such as a vacuometer, a pressure gauge, a dif- manometer, a barometer and a tonometer.
