A barometer is used in 2 ways.

First you keep it stationary. You record the pressure. If the pressure drops, it means, a storm is coming.

Second, in a car or airplane when the barometer falls, it means you are getting higher. When the barometer drops, it means you are getting lower.

How can you measure air pressure?

Air pressure is typically measured using a barometer, which can be either an aneroid or mercury barometer. An aneroid barometer uses a flexible metal box to detect changes in air pressure, while a mercury barometer measures pressure by the height of a column of mercury in a glass tube. Other devices like digital pressure sensors or weather stations can also be used to measure air pressure.

What kind of barometer measures air pressure by using a metal chamber that is sensitive to pressure changes?

The kind of barometer you are referring to is a aneroid barometer. It uses a metal chamber (an aneroid cell) which expands or contracts with changes in air pressure. This movement is then converted into a reading of air pressure on a dial.
