The mercury barometer is the standard instrument for atmospheric pressure measurement in weather reporting. The decrease in atmospheric pressure with height can be predicted from the barometric formula. The unit mmHg is ...Barometric pressure, also known as atmospheric pressure, is a term used to describe the measure of the amount of atmospheric weight pressing down upon a certain point on the Earth's surface. Barometric pressure takes its name from the barometer, which is a device that is used to measure the atmospheric pressure in an area.

A barometer is a simple instrument for measuring atmospheric pressure. A barometer can be made by filling up a long glass tube with mercury, then turning it upside down in a bath of mercury as shown. The space at the top of the barometer tube is a vacuum and exerts no pressure on the mercury column.Air pressure is referred to as barometric pressure because barometers are the instruments used to measure it. Two things affect the barometer's reading: the high or low air pressure caused by weather, and the air pressure caused by the station's elevation above sea level.

That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes.An aneroid barometer is a device used for measuring atmospheric pressure without the use of fluids. It typically consists of a sealed, flexible metal box known as an aneroid cell. This cell is designed to expand and contract with changes in atmospheric pressure. The aneroid cell is made from an alloy that is sensitive to pressure changes.
