SI unit is the Pascal. The US uses psi (pound per square inch). The last q depends a little on who is asking. It does have the advantage of showing the components. Pascal is equal to a Newton per meter cubed which is not obvious by looking at unit. I suppose its also better for measuring pressures over smaller volumes.
Millibars. Inches of mercury or feet of water
atm (atmosphere) or millimeters of mercury (mmHg)
Energy
pascal
E(nergy) is measured in J(oules).
inches in mercury and millibars Barometers .
There are many units of pressure. Some common ones are:AtmosphereBarInches of MercuryPascalNewtons per square millimeterPounds per square inch
Probably a mercury barometer and a aneroid barometer. -adrian
Units of Pascal, Torr, or Bar are commonly used to measure pressure. These units represent the force exerted by a fluid or gas over a given area. Pascal is the SI unit, Torr is commonly used in vacuum measurements, and Bar is used in meteorology and industrial applications.
The two most common units used for air pressure in weather reports are: Inches of Mercury and Millibars.
The answer to this question is, the Mercury and aneroid barometer
The two most common units used for air pressure in weather reports are: Inches of Mercury and Millibars.
There are several very commonly used units to measure pressure. Probably the most common is atmospheres (atm). The other very common units are millimeters of mercury (mm Hg), which is the same as torr, and then there is kilopascal (kPa).
Chemistry uses both the metric system and the International System (SI) units of measurements. Air pressure equations are measured in atmospheres (ATM) and Pascal's (Pa) for physical chemistry.
Pressure is measured by a pressure gauge, pressure transducer or other similar device. Once measured, the pressure can be expressed in any one of a number of different units. The "kilopascal" is one unit that's commonly used.
Pressure is often measure in units of force per area. In the standard system of units, the SI, that would be Newton / meter2 - this unit is also called Pascal. Other commonly used units are bar (equal 100,000 Pascal), and atmosphere (the atmospheric pressure under standard conditions - close to one bar).
cubic inches or cubic feet are most common. For sand, stone, etc. cubic yards is common.
