@inanimatecarbongod @hildabast there are another set of standards for this - the EL Reg units.
However for celestial bodies the largest volume unit the 'Olympic swimming pool' is still a bit small so I expect we would need to invoke k, m, g and t multipliers as well.
They also have walnuts, grapefruit, chicken's eggs and footballs.
The weight measures are a bit more exotic: badgers, great white sharks, skateboarding rhinos, Australian trams and LINQ hotel recycling.
