Bar is from the Ancient Greek word βάρος (baros), meaning weight (of the atmosphere in this case).
1 bar ≡ 100,000 N/m² = atmospheric pressure on Earth (at an altitude of 111 metres at 15 °C). Introduced by the Norwegian meteorologist professor Vilhelm Bjerknes, based on the word barometer, which dates back well over a hundred years further.

A millibar is 1/1000th of a bar, nothing to do with mm.

Thanks for clearing this up Nigel. How fabulous that the self appointed smartest guy in the room always has internet searches available when he wants to present quotes like this without acknowledging their source.
