Well it started out to simply show that physics has become entangled
with all sorts of loose ends because the metric system made artifacts
for weights that were to be used to calibrate weight scales
internationally.

These artifacts - the gram and kilogram - were to be the standard
units of mass, and the fundamental units of the metric system were
chosen to be: Length; Mass, and Time.

I've been trying to argue that the fundamental units of physics are:
Length; Force [& weight], and Time; with mass being a ratio of force,
divided the acceleration that it causes; which ratio [f/a] is equal to
the weight [w] of an object; body, or mass of matter, divided by the
acceleration [g] at which it will free fall at the location of the
scale on which it is weighed: That the measure of mass is inertia [m =
f/a = w/g].

None of you will have it, and keep knocking me down! So in my best
interests; I think I'll "cool it" for a while;^)

Making the distinction between mass and weight is critical for understanding physics, but not for everyday behavior involving measuring things in pounds; after all, in extending the popular concept of a "pound," different physicists made a distinction between mass and weight differently such that there is no accepted standard. ...
