I don't think that's relevant for Register units. Clearly there's a standard brontosaurus somewhere, for instance, otherwise how could we have the conversion table? However, sorry, I was wrong about the football pitch, at least as a unit of area, equal to 194.89nWa per the original article: https://www.theregister.com/offbeat/2007/08/24/so-whats-the-...
You're not wrong! Personally, I like to use penguin as a measure of height. Everybody knows how big a penguin is, right? It's pretty standard.
to clarify for those of a nautical bent - that's about half a blue whale for about 4/5ths of a dozen nautical miles
For anyone confused, British people would generally use tonnes (or tons, but maybe not know the difference exactly) and miles.
I initially read the title as 55,000 one pound stones. I was thinking, huh that does seem like a lot of work. (>▽<)
