The bar is a metric unit of pressure defined as 100,000 Pa (100 kPa), though not part of the International System of Units (SI). A pressure of 1 bar is slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar).
The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m 2, or kg·m −1 ·s −2). This name for the unit was added in 1971; [7] before that, pressure in SI was expressed in newtons per square metre. Other units of pressure, such as pounds per square inch (lbf/in 2) and bar, are also in common use.
Barg may refer to Barg, Iran, a village in Razavi Khorasan Province, Iran; Barg, South Khorasan, a village in South Khorasan Province, Iran; Kabab Barg, Persian-style barbecued lamb, chicken or beef kebab; Barg, a unit of gauge pressure, i.e. pressure in bars above ambient or atmospheric pressure; see Bar (unit)#Absolute pressure and gauge pressure
The first group of metric units are those that are at present defined as units within the International System of Units (SI). In its most restrictive interpretation, this is what may be meant when the term metric unit is used. The unit one (1) is the unit of a quantity of dimension one. It is the neutral element of any system of units. [2]
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

The barge, which is owned by Martin Petroleum, has a 30,000-gallon capacity, but it's not clear how much leaked into the bay, said Galveston County spokesperson Spencer Lewis. He said about 6.5 ...
This use of the unit of pressure provides an intuitive understanding for how a body's mass, in contexts with roughly standard gravity, can apply force to a scale's surface area, i.e. kilogram-force per square (centi-)metre. In SI units, the unit is converted to the SI derived unit pascal (Pa), which is defined as one newton per square metre (N ...
