I think I've solved my own problem: but I would appreciate all comments and criticism: It seems that, maybe, all physical equations must, ultimately, be numerical, and therefore - ultimately dimensionless. I suggest my mistake is in thinking that the M, in F=Ma, is fixed - as the unit...

But this doesn't mean M(kg) = M(g)/1000 Because that means 1000kg = 1g Do you see the problem? In this verbal equation, *in* must stand for divide by - not multiply. If we apply the rule that *in* stands for divide, the verbal equation now works: M/kg = (1/000) M/g This is consistent...

I have a problem that might sound simple, but has been bugging me for months. In a physical equation, the units are regarded as multipliers - so to take a very simple example in SI: 1) F[N]=M[kg]a[m/s2] And, of course, [N] is equivalent to [kg][m/s2], so all is well. Here's my...
