The standard atmosphere is a unit of pressure and is defined as being equal to 101.325 kPa. Pressure is the force F per unit area A applied to an object in a direction perpendicular to the surface. p = F / A.
Yes, mm Hg (millimeters of mercury) is a unit of air pressure commonly used in barometric pressure measurements. Milliliters (mL), on the other hand, is a unit of volume and is not used to measure air pressure.
air pressure is the firce exerted by moving air moleculesAir pressure is the air around you. Air pressure can pushing every where so the air from the top only dosent squish you into a pancake. Pressure is defined as force per unit area. The standard unit for pressure is the Pascal, which is a Newton per square meter.
millibars
Mine came new with air pressure in the bladder & no water in the unit so I would assume that you would pressurize the bladder with no water in the unit . Hope this helps .
the ancer to this question is milliliters

The force of air weighing down over a unit of area is called atmospheric pressure. This pressure is exerted by the weight of the air above that unit of area, and it decreases with increasing altitude.
(any unit of force) divided by (any unit of area)
A pound of air is NOT a measure of pressure. A unit of pressure would be a weight ( a force really) for instance pound by a surface (square inch for instance). Pound is a unit of weight only. At sea level on earth barometric pressure, 1 cubic metre weighs 1.2kg (or 2.64 pound). Which means 1 pound of air represents a volume of 0.379 cubic metre of air. This obviously varies with atmospheric pressure (the air pressure) and the gravitional pull. a pound of air would represent a much bigger (6 times bigger roughly) volume on the moon for instance.

The Newton [N] which can also be be written as [Kg* m/s^2]
The international standard unit for measuring pressure is the pascal. 1 pascal = 1 newton / square meter. A unit commonly used is the bar; 1 bar = 100,000 pascal; and that's the approximate air pressure at sea level. Older units that are still sometimes used include mmHg (millimeter mercury).
