does anyone have any suggestions for unhinged units to measure volumes of water?

I'm going to be adding liquid measurement to our water dispenser at the hackersapce and want to have it rotate through insane measurements

@darkuncle @alyx and there are two hogsheads in a butt!

@idiomatic @alyx The evidence in favor continues to accumulate.

Sesters

He that ys a gawner owght to understonde there ys in a tunne lx systerns and every systern ys iiii galons be yt wyne or oylle.

Translation:
He that is a gauger ought to understand that there is in a tunne 60 sesters, and every sester is 4 gallons, be it wine or oil.

@HollieK72 @darkuncle @alyx Incredible, thank you.

The conversion tables in that article are so handy! Finally, I understonde how to convert between puncheons and rundlets, so I won't be caught off-guard (off-gawned?) the next time someone asks.
