Mass is a quantity of matter; inertia is its measure |
A quantity of matter is not a fundamental measure; the measures of the
mass in a quantity of matter are the net force [f] exerted on, and/or
by it, divided by the acceleration [a] that is caused; which is equal
to the ratio of its weight [w], divided by the acceleration of free
fall [g] at the location of the scale on which it is weighed:
For any quantity or mass of matter, anywhere, anytime: These _ratios_
are Constants; called inertia [f/a = w/g]; which may be substituted
for any quantity or mass of matter, anywhere, anytime.
The equations: f = ma, or w = mg are strawmen:
f = [w/g]a, and w = [f/a]g!
Wake up and get a good breath of truth.

Inertia

Mass

"The time has come," the Walrus said, "To talk of many things:
Of shoes, and ships, and sealing wax, of cabbages and kings.
And why the sea is boiling hot and whether pigs have wings."
Makes about as much sense as Shead eternal struggle with inertia,
weight and mass.

"Note that the pound is not a unit of mass, but rather one of weight."

"The system of masses used in the United States for most common
commercial purposes based on the pound-mass and ounce and summarized
in the following table."
Eric Weisstein, the author of the pages you cite, struggles with
simple facts nearly as much as Shead does.
