density weighs 62.4 pounds; where the pound is a convenient quantity of

Other quantities can be derived from measures of these three quantities.
Such as a slug is the mass and/or inertia of the ratio of [1# per (1
foot/sec²)].
Furthermore every step we take, and every move we make is governed by the
inescapable force of gravity; which is the cause of free fall: Where the
acceleration of free fall is due mainly to the force of gravity.

I should add the Ampere definition is changed from that current when
maintained etc etc gives rise to a force of 2E-7N becomes a force of

Wrong. No amperes in the system Old Man was talking about. Didn't
you understand his second question?
I suppose it would be similar to the old three-base-unit cgs systems,
with the units of charge being erg^(1/2) cm^(1/2) and of electromotive
force erg^(1/2) cm^(-1/2). Except that unlike those cgs systems
where one of the three base units is a unit of mass, one of Dense
Donny's base units is a unit of force.

Well 1V = 1kg*m^2/(A*s^3)
using your formula Gene you would have units of ft*(lb*ft/s^2)^0.5 =
ft^1.5*lb^0.5/s
which is not the same units of voltage of M*L^2/(I*T^3)

Let's see--your M and L and I and T are *FOUR* base units. Shead's

A square Acre gives Acre^(1/2) = 209 feet, but cm^(1/2) is mind
boggling. One may as well institute a new unit, such as a unit of
charge. Consistent with cgs, Gaussian units include such as "esu"
and "statvolts", but someone has been reconfiguring history: Old
Man doesn't believe that "statvolts" preceded "volts". SI, with it's
three fantastical properties of free space, "ep0", "mu0", and "Z",
serves as nutrition for crackpots. [Old Man]

acceleration of free fall is due mainly to the force of gravity.
Hey Shead! How much is 120 volts in units of foot-pound-seconds?
What would Shead write on a 20 Ampere fuse? [Old Man]
2 seconds
"Attention!!!
If (20 * 6.24 x 10^18) charge events per second are exceeded,
for X seconds, this fuse will open the circuit."
The X depends upon whether the fuse is a fast or slow blow fuse.
=============
(voltage * charge^2 / acceleration) has the dimensions of
(foot-pound-seconds).
so we could say 120 volts * (n * 6.24 x 10^18) charge events per second )^2
= x foot-pound-seconds * acceleration
I'll leave it to old man to figure out the rest.
There's probably a nice equation somewhere that
shows how much electrons are accelerated by voltage,
that can be used to stitch this thing together.
A good place to find the equation might be
at some oscilloscope web site. (Tektronix maybe)
