TGM Usuel is a system of measurement consisting primarily of a dozenalized version of English units. All units are related to TGM units by simple dozenal-friendly ratios.

Conversion Factors Edit

For the sake of simplicity, the sizes of TGM Usuel units are constrained to the FS(2) series of preferred numbers. That is,

{1, 4/3, 3/2, 2, 3, 4, 6, 8, 9} × (power of twelve) × (TGM base unit)
