Millibar

From GAWDAwiki

A millibar is a unit of pressure that is equal to 1/1000th of a bar. There are 1,000 millibar in one bar. This unit is used by meteorologists who find it easier to refer to atmospheric pressures without using decimals. One millibar = 0.001 bar = 0.750 torr = 100 Pascals.^[1]
