A barometer displays the atmospheric pressure. The units can be: bar, mm Hg, hectopascal, and others.
If the atmospheric pressure increases it usually indicates good weather. The opposite if it decreases.

It displays approaching changes in weather, but does this by measuring changes in air pressure. A bar is a unit of pressure, hence the name Barometer

A barometer displays a reading of atmospheric pressure. The measurement units are either in millimetres or inches of a column of mercury, or milibars. A Pascal is a unit of pressure, meaning a pressure per square metre exerted by mass of one kilogram; in SI units a Pascal is defined as 1 newton/meter² or 0.01 millibar.

Air pressure. As such it can warn of low pressure (storms) or tell high pressure (fair weather).
