The Mercury barometer is a tool used by meteorologists and other scientists to find the air, or "barometric" pressure. Because mercury is liquid at room temperature, it can change shape due to changes in the atmosphere. Earth's barometric pressure is characterized as the downward force of air on the surface of Earth. If mercury is placed in a tube and the level decreases by a huge increment, it would show an increase in barometric pressure. Mercury barometers can also be used to detect incoming storms as right before a storm, the air pressure decreases drastically.

What are the uses of a Mercury barometer?
A Mercury barometer is used to measure atmospheric pressure.
What is the most commonly used barometer?
The most commonly used barometer is the mercury barometer.However, it is not easy to transport but it gives more accurate results. Another type of barometer is Aneroid barometer which is easy to transport and handle.
What is a mercury barometer used for?
Mercury barometer is used for measuring atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.
