Dozenal (Base Twelve) Arithmetic

Primel is a measurement system grounded in duodecimal or "dozenal" base arithmetic. Given the high factorability of the number twelve compared to ten, dozenal is arguably a more convenient base for human use than decimal. It is for that reason that so many historical systems of measure naturally incorporated factors of twelve. However, when they did so, it was only piecemeal. Primel can be characterized as a "dozenal-metric" metrology, similar to the Tim-Grafut-Maz (TGM) metrology devised by Tom Pendlebury. Like TGM, Primel systematizes its units around powers of twelve to the same degree that the metric system (now known as the International System of Units, or SI) systematizes its units around powers of ten.
