What is the name for pressure caused by the weight of the atmosphere?
Simply put, atmospheric pressure is the force exerted on a measuring point by the weight of the air molecules on top of that point. Standard atmospheric pressure, measured at sea level at 59F or 15C, is used as a reference point and is equal to 29.92 inches of mercury or 1013 millibars of pressure.
Why is the value of atmospheric pressure compared to mercury?
Atmospheric pressure will support a column of mercury to about 760 mm. Mercurial air pressure is described as '760 mmHg'. As air pressure changes , the height of this column will also change. If you did it with water, the column would have to be about 34 feet (10.2 metres) in height.
What is meant by atmospheric pressure is 1 ATM?
It just means that the pressure you're measuring is approximately the same as Earth's air pressure at sea level.
How many psi in 29.92 in hg.?
29.92 inches of mercury, which is the average atmospheric pressure on Earth at sea level, is about 14.7 pounds per square inch.
What is the absolute pressure at 20 inches of mercury?
0.67 atmospheres
If the atmospheric pressure is 29.4 inches of mercury what is the corresponding pressure of mercury?
If the atmospheric pressure is 29.4 inches of mercury the corresponding inches of mercury is: 880.
What does the pressure units in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of Mercury on a mercury barometer
What does the pressure units 30.03 in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of mercury on a mercury barometer
What does the abbreviation Hg mean in meteorology?
Inches of mercury, as it relates to atmospheric pressure.
If the atmospheric pressure is 24.9 inches what is the pressure in mm Hg?
18,920 mm of mercury at 24.9 ATM
What does a compound pressure gauge measure in?
The Compound Gauge measures above and below atmospheric pressure (in psig and inches of mercury).

What does mm-Hg means in nursing terms?
millimeters mercury? ____________________ "mm Hg" is the abbreviation for "Millimeters of Mercury. It is a measure of blood pressure. Millimetres of mercury (Hg is the chemical sysmbol for mercury). This is normally a measurement of atmospheric pressure - the number of millimetres of mercury in a sealed glass tube supported by air pressure. Standard atmospheric pressure (101.325kilo Pascals) is equal to 29.92 inches of mercury (inHg) or 759.968 mmHg.
What is measured in inches of mercury?
Those are (somewhat outdated) pressure units.
Barometric pressure ground level?
Atmospheric pressure varies with altitude and air density. Average sea-level pressure is 101.325 kPa (1013.25 mbar) or 29.921 inches of mercury (inHg) or 760 millimeters of mercury (mmHg).
What is meant by atmospheric pressure is 1 ATM?
It just means that the pressure you're measuring is approximately the same as Earth's air pressure at sea level.
