When you are measuring air pressure, you are measuring the force that the air is exerting outwards, on whatever you are using to compress it (since materials resist being compressed). For example, measuring the air pressure in a balloon is measuring the amount of force that the air is pushing against the material of the balloon.
This is usually expresed in Pounds per Square Inch (PSI).
The instrument used for measuring pressure is called a manometer.
The term for measuring pressure without considering the current atmospheric pressure is called gauge pressure.

An instrument for measuring atmospheric pressure, used especially in weather forecasting.
barometer is used to measuring atmospheric pressure. manometer is used to measuring the pressure of gases.
Two methods for measuring air pressure are using a barometer, which measures atmospheric pressure, and using a manometer, which measures the pressure of gases and vapors in a closed system.
a barometer is used for measuring pressure,the units for measuring pressure include atm,pascal,torr,mm of hg,bars.
