1 millibar (or hectopascal/hPa), is equivalent to 0.02953 inches of mercury (Hg). It is therefore only necessary to multiply a reading in millibars by the latter figure, to achieve the required conversion. E.g. for 1023 mbar, multiply by 0.02953=30.21 inches.
The answer is 0.0393700791974. We assume you are converting between inch mercury [0 C] and millimeter mercury [0 C]. The SI derived unit for pressure is the pascal. 1 pascal is equal to 0.000295299830714 in Hg, or 0.00750061561303 mm Hg.
