The SI unit of pressure is the pascal. 1 pascal is rather small, so normal atmospheric pressure on Earth is about 100 kilopascal.
However, any pressure units can be used; some that have been are psi (pounds per square inch), bar (defined so that average air pressure = 1 bar), inches (or millimeters) of Mercury (the pressure exerted by a column of liquid mercury of that height)or torr (1 torr = 1 mmHg);.

What uses air pressure to work?
air
Great masses of air molecules pushing down from adove?
It is AIR PRESSURE!!
What is air moves from a point at which air pressure?
high pressure to low pressure
How does altitude affect density and air pressure?
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.
When the air pressure in the lungs is greater than the air pressure outside the body you?
at higher altitudes the pressure of air is greater in our lungs as compare to the air pressure outside the body
What was the history of meserment?
Metallica
What has a meserment of 180?
180 is the sum of the 3 angles in a triangle.
What is the weather term of how heavy the air is?
Air Pressure
How is earths air pressure different from seas air pressure?
It is different in that the seas don't have air pressure. No air; no air pressure.
How does air pressure affect air movement?
Air pressure affects air movement because air moves from high pressure to low pressure. The air pressure pushes or will press the air around.
What uses air pressure to work?
air
What does high air pressure?
air pressure is the amount of air pushing down on you and high pressure is air that rises.
Compare air pressure on earth to air pressure on the moon?
The moon has no air pressure because the moon has no air.
How air density related to air pressure?
As air pressure pressure decreases with altitude, so does the densite of air.
The force exerted by the weight of a column of air on a surface is called?
Air Pressure The force exerted by the air above is called?
Great masses of air molecules pushing down from adove?
It is AIR PRESSURE!!
What does cold air have on air pressure?
Cold air increases air pressure
