tl;dr: v0.8 introduces a bunch of new archverse names after yov (yottaverse), changes arv^n to arv^(n-1), and adds a new system of names for very large amounts of mass that is not legitimately attainable yet.
The names in parentheses can be seen by setting the mass format naming to standard.
- 1 g (gramm)
- 1 kg (kilogramm) = 1,000 g
- 1 tonne = 1,000,000 g = 1,000 kg
- 1 MME (mass of mount everest) = 1.619e20 g = 1.619e14 tonne
