OK, guys (and gals)
I've watched the exchange on this topic with a mixture of dismay
(hoodwinking unsuspecting US visitors to Canada) and fascination (how can
there be so much confusion). Time to haul out my "Chem Rubber Handbook,"
that compendium that every chemistry student in college refers to when the
going gets tough. I quote, from the 42nd edition of the Handbook of
Chemistry and Physics (those of you who are familiar with this handbook will
realize that this edition dates me):
Ounce (Fluid) (U.S.):
1/128 or 0.0078125 gallon (U.S.)
0.03125 quart (liquid, U.S)
1/16 or 0.0625 pint (liquid)
1/4 or 0.25 gill (U.S.)
1.80469 cubic inches
8 drams (fluid)
480 minims
0.0295729 liter
0.295729 deciliter
29.5729 milliliter
29.5737 cubic centimeters
Ounce (Fluid) (British):
0.006240 gallon (British)
8 drachms (fluid, British)
480 minims
28.4130 cubic centimeters
I should add the conversion units for the avoirdupois ounce and the
apothecary, or troy, ounce, but suffice it to state that the avoirdupois
ounce are weights, not volumetric units.
To summarize, the US ounce is 29.5737 cubic cm; the British (Imperial) is
28.4130 cubic cm.
The CRC Handbook gives the following for gallons:
US gallon: 3.7853 liter
British Imperial or Canadian gallon: 4.54596 liters
Clearly, the way to go is to change over to SI units but some of us may
think that this is too sterile and more for Miata owners.
Now what was the question again? The volume of somebody's rear end? ;-)
