Although base-10 is the way we calculate, computers use base 2, so in some
ways the English System is far in advance of the metric. We use K's and Megs
these days, which are not quite M's and Millions. Metric proponents proudly
point to the fact that a liter of water weighs exactly a kilogram. Fair
enough, but "a pint's a pound the whole world round," or at least once was.
A fluid ounce of water weighs an ounce. The equivalence is present in both
systems.

Now, he states:

How can this be? A ounce is 28.3 g and a an ouncie fluid is 29.5 mL. A
pint US is 473 mL, a pound US is 454 g. For an ounce liquid to weigh an
ounce and a pint to weigh a pound, either an ounce fluid has to be 28.4 mL
or an ounce mass has to be 29.5 g. And as well, a pound must be 473 g, or a
pint must be 454 mL. In other words, their numeric values in grams and
millilitres must be the same.
And this doesn't take into account the imperial variation. If I was a
student and had been assigned to his class, I'd either request a transfer or
drop the class and get my money back. If this guy can't get simple
relations like this correct, he must have real trouble with the more complex
math.

Keiner ist hoffnungsloser versklavt als derjenige, der irrt�mlich glaubt
frei zu sein.
There are none more hopelessly enslaved then those who falsely believe they
are free!
