Warning: this sociology paper by Mike Michael is a rabbit hole, leading to other rabbit holes - fascinating, occasionally hilarious & sometimes downright bizarre...
It's about what the author calls "lay metrology".
That's describing measurements in terms that are presumed to give lay people a sense of the proportion - like saying something's "twice the size of Wales"....

@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.
