*** For conversion of direct to indirect or vice-versa, 'Conversion Constant' has to be used:
Count in Unknown system = Conversion Const. / Count in Known system
*** For conversion of direct to direct OR indirect to indirect, 'Multiplying Factor' is used in the following way:
Required count = Known count x Multiplying Factor
