Template:Convert/dimension code

The parameter  in the convert unit templates specifies dimension. Base dimensions are encoded with prime numbers. Other dimensions are the corresponding products of the base units and/or their inverses. The table below lists the codes used. Eleven is used to distinguish most dimensionally equivalent units which are conceptually different (e.g. pressure vs energy density). An exception is made torque vs energy, which uses one hundred and one to accommodate the dual purpose units such as foot-pounds force used in the imperial/US system.
