For people outside the USA, the idea of mixed units, or even just the various interpretations of imperial/archaic, I suspect isn't as intrinsically droll as it perhaps is from within a culture that's still trying to work out whether to adopt a basic measurement system in use across 95% of the planet.

However, gripes aside, for fruity measurements you may wish to adopt (read: you may not be aware of, but if you aren't, I suspect you'd approve) the FFF [6] measurement system.

The above relationship would be expressed as 54 furlongs of mycelium per 1.2283533E-7 cubic furlongs. (I think)

I thought that was funny. Too many fragile egos on HN with no sense of humor.

I`m still counting the inches in a light-year, so the nautical leagues perspective made me giggle a little.

I try to find excuses to express density in an area in terms of miles per gallon, but it turns out to be surprisingly difficult.
