Advance warning of changes in atmospheric pressure can tell us what may happen with the weather. Example: a drop in atmospheric pressure indicates a storm of some kind is on its way.
Many do, but not all. Most barometers that people would have in their homes are aneroid barometers, which don't contain any mercury.
Barometers, Anemometer, Thermometer
Thetools scientist use are Barometers, Anemometer's thermometers Richter Scale
science is important in our life because we know that our movement were came from and all things.
Primarily so that there can be more Life.
There are two types of barometers, Mercury barometers and then Aenroid barometers.
mercury barometers and aneroid barometers both measure air pressure.
Mercury and aneroid barometers.

No! Barometers are not related to maths. They are devices used to measure atmospheric pressure... You may not be able to use barometers for maths project. - Abid
Pilots use barometers to see the air pressure from the plane.
They are more portable and can be used for airplane equipment
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.
