Because it has a high density... meaning that the volume increase or decrease due to altitude change is can be viewed in a practical sized barometer. If water, which had a much lower density, was used instead of Mercury, the barometer must be at least 15m high.
The barometer is used to measure air pressure, which can help predict changes in the weather.
The first barometer was made by Evangelista Torricelli in 1643. Torricelli was an Italian physicist and mathematician who created the barometer as a way to measure atmospheric pressure.
Evangelista Torricelli, an Italian physicist and mathematician, is credited with inventing the barometer in the 17th century. Torricelli's creation of the barometer was a significant development in the study of atmospheric pressure and weather forecasting.
1643. But there's lots more interesting history available in the wikipedia article about the barometer.

Air pressure is measured with a barometer.
A portable barometer that uses a small flexible metal box instead of liquid is called an aneroid barometer.
The aneroid barometer was developed as an alternative to the traditional mercury barometer due to safety concerns associated with handling mercury. Its development was also driven by the need for a more portable and reliable device for measuring atmospheric pressure that could be used in various settings. The aneroid barometer uses a small, flexible metal box instead of liquid mercury to detect changes in pressure, making it safer and more convenient for everyday use.
