Apparently you are claiming that pounds are not units of mass.

Where did you learn that?

Well, I learned that a Pound is a unit of Force.
Well, I learned that a Slug [pound mass] is Pound*acceleration.
Well, I learned that mass is pound*sec^2/foot.

Where did I learn this? What's my source? Physics 101, University
Physics, Sears and Zemansky, Addison-Wesley Publishing, 1956, Chapter 6,
page 94.

I hope tou don't need another reference?

Now, what's your real problem? What are you trying to say?

Can you quote it to me, specifically where it says that pounds are not
units of mass? I'll bet you just misunderstood what it said. I have
the 1970 edition of Sears and Zemansky myself, so I'm betting that if
anything, what it actually says is clearer in that older edition than
it is in the 1970 edition.

Pounds force do exist, of course. What I'm asking you to show me is
not that, but rather that pounds are not units of mass.

Sears and Zemansky didn't lie about this in 1956. They might have
been dishonest and deceptive about it, not concerned enough about the
possibility that fools like you would misinterpret what they said or
actually encouraging such misinterpretation. But they didn't lie
about it. Some textbooks today might actually lie about it (or,
alternatively, their authors are too poorly educated to know any
better--take your choice).

Being the skeptic that I am, how can I convince myself that that is
true? Is there some textbook, or something from some national
standards agency, that would help me verify this?
