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.
Standard sea-level pressure is expressed as 1013.2 millibars. Isobars are lines on a weather map that connect places of equal air pressure. A mercury barometer measures air pressure using a column of mercury in a glass tube that is sealed at one end and inverted in a dish of mercury. mercury barometer measures atmospheric pressure in inches of mercury, the height of the column of mercury in the barometer. Standard atmospheric pressure at sea level equals 29.92 inches of mercury.
