A barometer measures barometric pressure, that is, atmospheric pressure. Because air flows from high pressure areas to low pressure areas, rising or falling barometric pressure tells us that we should expect a change in the weather. For example, a storm is often preceded by a drop in barometric pressure. A barometer is an indispensable tool for a meteorologist, a captain of a ship, or anyone else who needs to predict the weather.
It depends what you use it for, its not much good for opening bottles of beer, playing music or generally attracting members of the opposite sex but if you want to measure atmospheric pressure its pretty useful ;)
It is used to measure atmospheric pressure.
A barometer measures atmospheric pressure. A link is provided to the Wikipedia article on the barometer, and you can find that link below.
The barometer is used to measure atmospheric pressure.
A barometer is an instrument used to measure atmospheric pressure
Barometers indicate air pressure. Usually high pressure predicts dry weather, while low pressure is associated with wet weather.
A barometer measures changes in air pressure. A barometer can therefore be used as an aid to forecasting the weather.
It measures air pressure, and can be used to gauge altitude and to predict weather.
so they can measure air pressure
Some of the weather equipment are: Radars, Barometers, Thermothers, and Rain Gauges. This is just some of many and the world advances.
They allowed scientists to measure pressure.
thermometers, wet-dry bulbs and barometers
A barometer is a weather tool that shows you air presser.
Barometers measure air pressure.
Digital barometers, much like analog barometers, are used to forecast the weather using humidity, air pressure, and dew point. This answer needed a few more characters.

They are more portable and can be used for airplane equipment
There are two types of barometers, Mercury barometers and then Aenroid barometers.
The pressure of air.
it measure the atmosphere.
they are used all over the world

Barometers are used to measure pressure.
mercury barometers and aneroid barometers both measure air pressure.
