If the pro-metric crowd gets their way, English units will become
obsolete. Would their demise mean they "can't have been that useful?"

Sounds wonderful! And you want to keep this monstrosity and think that
trying to simplify is a "communist plot"?

Into 640 pieces? What's so special about 640?

Part of the World-wide communist conspiracy to subvert the simple God-
given American units, right?

No, no. I agree. We should keep the Imperial system, which is "an
unfortunate result of trying to put the Anglo-Saxon distance units
into the Roman-based system", and the "aberrant British units".

Or do you propose to eliminate all units that come from Britain and
just keep the God-given American system, which has been given to us
not by Brits but by Native Americans?

It is a very well established fact that they didn't even have fluids
in Britain until we Americans introduced them to fluids in 1776.

Brilliant! And the idea of using unrelated units for length, for area
and for volume - that's an extra brilliant touch. Makes it so easy to
compute area and volume from side length measurements!

Oh, come now, only the British could make a horse drip oil.

Because anyone who has to do technical work needs to
know a bunch of physical constants. If he happens to
live in the USA it is no burden to know a few
conversion factors.

For accurate work, tools are available.

$ units 'atm' 'pascal'
* 101325
/ 9.8692327e-06

$ units 'mile^3' 'cc'
* 4.1681818e+15
/ 2.3991276e-16
