Any formula for them is incomplete without it! Metrics ignored it, hoping it would go away because it complicates their nice neat system of tens; but it can't and won't!
The reason I've 'failed to respond' to the post that you've appended, is that I didn't get it: Thanks for doing so.

No, I'm trying to show that mass isn't fundamental: That mass (m) is equal (equivalent) to the ratios w/g = f/a! This makes mass superfluous because w/g = f/a is a complete formula; a complete equation that stands on its own!
Also: By transposition of m from m = w/g = f/a: we get w/mg = f/ma: From which m cancels!
Do you consider weight more >'basic' than mass, or just that the concept of mass is just faulty?? For the very introductory physics student (the only one who >would always be dealing with a constant g=9.8 m/s^2=32 ft/s^2), I don't think eliminating mass would simplify matters. Momentum >would now be p=wv/g. Does g play any role in the situation?
If not you'd just have p=wv; which is incomplete!
>When I first derived equations, I'd ask, what does force vary with?
You should have answered yourself: That (net) force (f) varies in proportion to the acceleration (a) that it causes; just as the weight (force) exerted by a body varies in proportion to the free fall acceleration (g) at the (time and) location where it is exerted.

Light's way too fast for me, I'll keep my suspicious mind open to whatever turns up.
