"Work: An appropriate unit of work is the "barn-yard-atmosphere" (equal
to 9.3 * 10^-24 Joules)"

Somehow, it's germane to this discussion.

Yes, and not only because it explains the odor pervading Shead's
threads. It is especially apt since Dense Donny is always bitching
about some unit being "too big" or "too small"--this unit is just the
right size so that we can measure the work Dense Donny Shead does, in
nice small numbers without having to resort to scientific notation.

Did Dumb Donny shitHead comment on it?

[(1000 m/km)(100 cm/m)]^3 = 10^15

Let's put Dumb Donny shitHead in perspective: null point. I could
have said a million and it would have made no difference. He's an
undeducated senile psychotic. He blows it out his ass because being
whipped is better than being forgotten. The First World's infatuation
with prolonging worthless life at chronic immense expense is
pathological. There will be payback.

Oh, one other note. You stated that Napolean had reinstated the original
units. This is only partly true. He reinstated them, but with new values,
tied to the metric units. So the "pied usuel" (foot) was 1/3 metre.

It's an obvious question. If there is a method of deriving everything
from the fundamental units of time, force, and length, then one
of those derivations includes either luminous intensity or
luminosity or something of that ilk. Surely there is a quantitative
measure that, using nothing but the three fundamental units,
can derive the luminous intensity of a light source, much like
one can derive pressure by dividing force by area, or
energy by multiplying force by distance.

Or perhaps you'll just have to relax your constraints and add
luminosity as a fourth basis unit; ditto for current,
substance amount (moles, usually), and temperature.

As it is, in SI if one assumes a 540 terahertz
monochromatic lightsource with no loss of energy
whatsoever, the computed value is simply
4 * pi * 100 * 683 = 858,300 candela, give or take.

Simple, no? :-)

You keep referring to your age. If you think you're too old to think
straight, then don't and keep sci.physics out of your thought experiments.

You're a troll, a boring one. I'm wrong to answer your mail but perhaps
you didn't realise you were one yet.

An average 14-year old can understand the use of the SI-system, why can't
you? Why do you insist on impossible hypothesises you can't prove?
