Follow this closely, particularly if you're American, and therefore have
funny ideas about Imperial Volumetric Measurements :-)

A (UK) gallon of water (at somewhere close to freezing) weighs 10 lbs.
10 lbs is 160 ozs
Therefore 1 (British) pint of water weighs 20 ozs.
This is the origin of there being 20 (fluid) ozs to the pint.

A pint of water (at least in the UK) is 568 or thereabouts grammes of water.
(SG 1gm/cc at somewhere around 0 deg C) so it occupies around 568 ml.

Therefore 20 (fluid) ozs (which is solely a volumetric measurement except
where water is concerned) equates to 568 ml.

There :-) Simple, and relatively painless, wasn't it?
