>...The Canadian gallon is the Imperial gallon, prior to both Canada and the UK going to SI units.

Canadian gallon is not the same as UK gallon. From my trusty HP48, it says 1_galC = 4.54609 liter, while 1_galUK = 4.546092 liter. So they are different.

Volume is one of the most difficult common unit to measure. Graduated, certified volumetric wares are expensive. hdtran touched the issue above, but I just want to add that temperature and to a lesser degree, pressure, has greater effect on the volume than anything else, such as dissolved gas or impurity. There are lots of intermolecular space between water molecules, although less so than solide ice.

Oh, Matt, regarding Bar Pint, I was a restauratur at one point you know. It is not a "standard" per se, but a common trick to get less liquor into the glass. We cheapskates do many other things to get more profit out of the already most profitable operation in restaruant. Other trick that you may be aware of is the use of specific ice cube that displace most liquor, without giving the impression of too much ice. There are also "trick" glass that some bar use... every milliliter counts

It always cracks me up when customers say "oh yeah, make it strong" or "use less ice and pour more alcohol"...Uh, sure. You don't go into MickeyD's and say "Hook a dude up and throw on an extra patty for me, would ya?"
