What is the pressure bar?

PSI means pounds per square inch, as you probably know.

The bar does not represent anything, it is a unit of pressure that is approximately equal to the atmospheric pressure at sea level. Atmospheric pressure is sometimes called barometric pressure, hence the bar per SRT.

Several units are commonly used to measure pressure. It is common to express only certain dimensions in certain units, for example, human pressure is measured in mm Hg (120/80 mm Hg) and air pressure is measured in mm Hg (760 mm Hg). Is measured. (Mercury column) Other pressure units are kg / cm2, pounds per square inch (PSI), pascal, tour, bar, etc. The bar represents the level of the environment. It is commonly used to measure hydraulic and steam pressure. Show the environment multiple times. For example, say 4 times that it is four times more atmosphere.

Bar (symbol bar), disbar (debar symbol) and millibar (MBR symbol, also MB) are units of pressure. They are not SI units or CGS units, but are acceptable for use with SIs. Bars are often used to describe pressures because they are compatible with environmental pressures and are legally recognized in EU countries. [1]

Bar, Deckbar and Millibar are defined as:

1 bar = 100 kPa (kilopascal) = 1000,000 dyne per square centimeter (BARC)

1 bar = 0.1 bar = 10 kPa = 100,000 den / cm

1 MBR = 0.001 bar = 0.1 kPa = 1 hpa = 1000 den / cm

(One pascal is one newton per square meter).

For example reading: 1 atm = 1.01325 bar = 1.01325 x 105 pa = 1.01325 x 105 N / m2 pressure


The word about comes from the Greek ب ¿Ã (barus), which means heavy. The official symbol is the bar, the first B is now obsolete but is still often seen in MB instead of the same member for Millibar.

The bar and malibar were introduced by Sir Napier Shaw in 1909 and adopted internationally in 1929.

Atmospheric pressure is often expressed in millibars, with a surface-to-surface pressure of 1013.25 MB (HPA), equivalent to 1.01325 bar. Although Millibar SI is not a unit, it is still used locally in the Meteorological Department to describe air pressure in some countries. The SI unit is Pascal (Pa), where 1 Amber = 100 Pa = 1 HPA = 0.1 KPA. Meteorologists around the world have long measured air pressure in Malabar. After the introduction of SI units, others used the hecopascle (equivalent to millibars) to maintain the same numerical scale. Similar kilopascular pressures can be found in almost any other area where hecto has never been used before. Specifically, the Cayenne weather report uses a clopascal [2] (also called a centibar).

The U.S. is familiar with U.S. reports of hurricanes and other hurricanes where low core pressure often means strong winds and hurricanes.

Pressure gauges usually measure atmospheric pressure (about 1 bar). It is a pressure gauge and is indicated by a slash, often written without it, referring to the pressure gauge bar and sometimes by a symbol such as a slash (G). For example, if someone says that the pressure on your car's tires is 2.3 bar, it usually means a pressure gauge: tire pressure is 3.3 bar, but only 2.3 bar of environmental pressure scale. There is a humometer. . Demonstrate in practice. When absolute pressure is required, carbon or bar (a) is sometimes given as absolute bar. It is now advised not to change the unit of measurement for this purpose as it is preferable to test the physical properties, such as pressure is 2.3 bar, absolute pressure is 3.3 bar. [1]

In water, estimates between changes in pressure in decibers and changes in sea level depth in meters. Numeric correspondence exists. As a result, decibar is widely used in oceanography.

Unicode has the role of MB: (Ã £ Â), but it exists only because of the old compatibility of Asian encoding. There is also a slash character:
