Force per unit area exerted by the air above the surface of the Earth. Standard sea-level pressure, by definition, equals 1 atmosphere (atm), or 29.92 in. (760 mm) of mercury, 14.70 lbs per square in., or 101.35 kilopascals, but pressure varies with elevation and temperature. It is usually measured with a mercury barometer (hence the term barometric pressure), which indicates the height of a column of mercury that exactly balances the weight of the column of atmosphere above it. It may also be measured using an aneroid barometer, in which the action of atmospheric pressure in bending a metallic surface is made to move a pointer.

The exact value used for the Standard Atmosphere is 1013.25 mbars ou HectoPascal.
Using the value of 1 Bar is incorrect in physic's terms. It is just an approximation.

1 atm (atm stands for atmosphere, this was one hella ez question lol)
or 760 torr (mm of mercury)

1 atm or 101.3 kPa or 760 mm of mercury in a barometer.

all these answers are correct except if your standing on a volcano that is about to blow...the other variable is the lunar cycle

scott's correct, but most people recognize it as 14.7 lbs/in^2
