Congolese Empireball/Metric System

This is the metric system of the  Congolese Empireball. It was used by 91% of the indigenous tribes.

Why using this?
After the  anarchy, the newer tribes have now forgotten the use of metric system. He then wants to make it more traditional, and   tribe friendly one, so yeah, he makes it.
