Millibar (Metric), pressure
The bar (symbol bar) and the millibar (symbol mbar, also mb) are units of pressure. They are not SI units, but accepted (although discouraged) for use with the SI. The bar is still widely used in descriptions of pressure because it is about the same as atmospheric pressure.
