Universal measurement system

The universal measurement system or UMS, but even though it’s called the universal measurement it’s not actually universal at all, only used on core planets, it is used for a more precise measurement. Planets like jamim and earth still use their regular measurements but use the UMS more. The UMS consists of 5 measurement systems measured in giliomiter, these 5 are listed as GG, AG, FG, MG, and OG
