Why do Aussie weather presenters use hectopascals instead of millibars in their weather forecasts?

    Because it's pretty much the same thing, but the (hecto)pascal is officially part of the SI-system

    The millibar is a non SI unit, representing 100 Pascals of pressure, or 1/1000th of a bar that represents 100000 Pascals. It's not obvious that something called a bar is 100000x a unit and a 'milli'bar is 100x a unit.

    The SI unit is the Pascal not the bar. A hectoPascal is, for anyone brought up in the metric/SI system, obviously 100 Pa.
