Any pushing force measured per unit area is termed as pressure. So the force may be the weight of a column of liquid or gas. Or the change in momentum of impinging particles per unit time on the plane. This will be equally balanced by the pressure exerted by the column of mercury. Hence the pressure is given in the familiar unit of height of mercury such as 760 mm of mercury(Hg) for normal atmospheric pressure.
--------------------------------------
The SI unit for pressure is pascal (N/m2), with the symbol Pa.
1 Pa = 10e-5 bar = 1,0197.10e-5 at; 1 mmHg has 133,322387415 pascals.
Air pressure is typically measured using a device called a barometer, which can be either aneroid or Mercury-based. Aneroid barometers use a small metal box while mercury barometers use a column of mercury to determine air pressure. Other methods include using electronic sensors in digital barometers or weather stations.
With a thing called a barometer. In its original form, still used for scientific purposes, it is a U shaped glass tube, closed on one side, and filled with mercury. The air pressure shifts the mercury level. Sure they have an explanation on wikipedia.

Air moves from a point at which air pressure is to a point at which air pressure is?
higher. This movement of air is driven by the pressure difference between the two points. The air flows from areas of higher pressure to areas of lower pressure in an attempt to equalize the pressure.
A barometer is an instrument used for measuring water pressure?
A barometer actually measures atmospheric pressure, not water pressure. It is commonly used in weather forecasting to determine changes in air pressure.
What weather instrument measures air pressure?
A barometer is the weather instrument used to measure air pressure. It can help predict short-term changes in weather such as approaching storms or clearing skies.
Why does the air over the sea land move towards the sea?
high preasure over the water leading to land in the opposite dirrection but not always.
Is an air intake temperature sensor the same as an air charge temperature sensor?
No, they are not the same. An air intake temperature sensor measures the temperature of the air as it enters the engine intake, while an air charge temperature sensor measures the temperature of the air after it has been compressed by the turbocharger or supercharger.
What is air preasure?

How does an open tube manometer work?
it measures the difference in preasure one arm of the tube is opened and the other is attched with a vessel like structure which help to measure the preasure the difference in liquid level represents ' the difference in preasure
Who invented the bourdon tube?
Eugene Bourdon 1849 France measures the preasure of liquids and gasses
Where is the air conditioner filter?
It is on outlet of the High preasure side
Where is air conditionEr filter?
It is on outlet of the High preasure side
Air moves from a point at which air pressure is to a point at which air pressure is?
higher. This movement of air is driven by the pressure difference between the two points. The air flows from areas of higher pressure to areas of lower pressure in an attempt to equalize the pressure.
Are the most important properties of an air mass its temperature and amount of water vapor?
no it is not its preasure
What are you measuring when you measure air preasure?
The difference in pressure between absolute and gauge pressure.
Aneroid barometer measures air pressure with?
barameter measures air pressure barameter measures air pressure
How do you make smoke come out of your mouth?
put air in your mouth and then put preasure in your mouth and then cluck
What is the working principle of inclined tube manometer?
For a very basic explanation, a manometer measures the pressure differential between a closed pressure applied at one end and an open pressure at the other. For example. If you have a typical u-bend manometer and you apply an air pressure at one end, the liquid will raise correspondingly, as the pressure on the closed side increases more and more above the ambient air pressure. The amount it rises depends on the density of the liquid used and the diameter of the tubing. So basically a manometer uses the height of a liquid to translate the amount above ambient air pressure, which is considered zero, of your pressure source.
A man turns a bucket of water upside down but the bucket remains full the bucket has no lid the water is not frozen the man is not in space or not swinging the bucket around?
when a man push the tumbler up side down than the air is blocked inside it and than the air preasure becomes so high in the tumbler and then the air preasure of outside is lower than the inside and than theair preasure inside the tumbler push the tumbler up.
