Barometric pressure (also known as atmospheric pressure) is the force exerted by the atmosphere at a given point. It is known as the weight of the air. A barometer measures barometric pressure. Measurement of barometric pressure can be expressed in millibars(mb) or in inches or millimeters of mercury (Hg). Normal pressure at sea level is 1013.3 millibars or 29.92 inches of mercury. Fluctuations in barometric pressure are usually a sign of weather conditions.
In simple terms, atmospheric pressure is also the same as air pressure. To imagine clearly, what atmospheric pressure is, simply think of a force in the atmosphere that is applied to a specific area. A barometer is an instrument that measures atmospheric pressure. Atmospheric pressure can be calculated. In 1641, Evangelista Torricelli made an experiment on measuring the atmospheric pressure. On his experiment, he used a tube sealed at one end. Torricelli immersed the tube in a container of mercury.
