TRWTF, of course, is the continued use of imperial measurements by the US. Are they not the only ones who still use it still?
As no one else uses it, I guess they are free to make them whatever they like!
On a not unrelated matter, I think that we here in Australia should make our own measurement system. As it seems that every area of water is measured in numbers of Sydney Harbours it could fill(or could fill it), we have the obvious measurement for fluid volume.
Anyone want to by me a picoSydHarb of beer?
