DefinitionMillibar Gauge is a unit of pressure relative to atmospheric pressure, scaled to millibar.
Like BAR_GAUGE, MilliBAR_GAUGE represents the difference between the measured pressure and the local atmospheric pressure.
No conversion multiplier or offset can be provided to convert MilliBAR_GAUGE to absolute pressure units like MilliBAR or PA.
Therefore, qudt:conversionMultiplier is set to 0 to indicate that no direct conversion is possible.^^http://qudt.org/schema/qudt/LatexString
