Silgyptian Measurement System - Conversion.

8,000 years before the birth of Christ a theological scientist name Sil Hamptos helped to re-define or more accurately 'Convert' the current scale of measurement being used by the Terran majority in a universal language of numbers. Applying the oldest of Terra's languages and methods of measurement, Sil combined the established rule of Palamenarian distance. Thus was born the Silgyptian System. According to Iropesede tribal members - the measurement of the Irile was established from the distance of the humanoid Iris. 

In a society dealing with over 300 species ( all humanoid ), Silgyptian law of distance seemed universal in its application.
