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.
Convert the units of the conical taper so that all units are the same. If the taper unit is inches per foot, divide by 12 to make it inches per inch. Three inches per one foot would equal 0.25 inches per inch. Visualize a cross section of the cone with the length being the height and the diameter being the base.
