What Does Bar Stand For
What is a pressure bar? 3
On the manometer it has PSI and BAR, which means 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, i.e. bar per SRT.
There are several commonly used units for measuring pressure. It is common to express specific dimensions only in specific units, for example, human pressure is measured in mm Hg (120/80 mm Hg) and environmental pressure is measured in mm Hg (760 mm Hg). (Mercury column) Other pressure units are kg / cm2, pound per square inch (PSI), pascal, tour, bar, etc. The bar represents the surface of the environment. It is commonly used to measure hydraulic and steam pressure. Show the environment multiple times. For example, 4 times say four times more atmosphere.

Bar (symbol bar), decibar (symbol of D bar), and millibar (symbol of M bar, also MB) are units of pressure. They are not SI units or cgs units, but are accepted for use with SI. Bars are often used to describe pressures because they are compatible with environmental pressures and are legally recognized in EU countries.

Bars, DC bars and Milli bars are defined as:
1 bar = 100 kPa (kilopascals) = 1,000,000 witches per square centimeter (Bariaceae)
1 dbar = 0.1 bar = 10 kPa = 100,000 dyn / cm2
1 mbar = 0.001 bar = 0.1 kPa = 1 hPa = 1000 dyn / cm2
(One pascal is one newton per square meter).
Example reading: 1 atm = 1.01325 bar = 1.01325 x 105 Pa = 1.01325 x 105 N / m2 pressure
The word Barre comes from the Greek ²ÃÂ¬ÃÂ Â¿ÃÂ, (baros), meaning heavy. The official symbol is the bar, the first b is now obsolete but is still often seen in mb instead of the corresponding mbar.
The bar and malibar were introduced by Sir Napier Shaw in 1909 and adopted internationally in 1929.
Atmospheric pressure is often expressed in millibars, the standard pressure at sea level is set at 1013.25 mbar (hPa) equal to 1.01325 bar. Although Millibar is not a unit of SI, it is still used locally in some countries to describe air pressure. The SI unit is Pascal (Pa), where 1 mbar = 100 Pa = 1 hPa = 0.1 kPa. Meteorologists around the world have long been measuring air pressure in millibars. After the introduction of SI units, others used hectopascals (equivalent to millibars) to maintain the same numerical scale. Similar klopascal pressures can be found in almost any other area where the prefix Hecto is almost never used. In particular, the Caian Weather Report uses clopascles  (also called centimeters).
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 relative to atmospheric pressure (about 1 bar). It is a pressure gauge and is represented by a bar, usually written without it, which means pressure gauge bar, and sometimes with a symbol like bar (g). For example, if someone says that the tire pressure of your car is 2.3 bar, it usually means a pressure gauge - the pressure inside the tire is 3.3 bar, but only 2.3 times the pressure. The bar happens. Environmental, scale is gauge pressure. exhibition . When absolute pressure is required, carbon or bar (a) is sometimes given as absolute bar. It is now advisable not to change the unit of measurement for this purpose as it is better to examine the physical properties, for example high pressure is 2.3 bar, absolute pressure is 3.3 bar. 
In water, there is an approximate numerical correlation between the change in pressure in decibars and the change in sea level depth in meters. As a result, decibar is widely used in marine science.
Unicode has the letter mb: (£ Â), but this is only for compatibility with older Asian encodings. There is also a slash character:
