OK. I am trying to understand the relationships between Planck length, Planck mass and Planck volume. The measurements are so small and have a standard uncertainty I was thinking I could scale them up somehow to say make 1 Plank volume equal to 1 cubic metre for convenience and then derive the other units from that. Don't ask me why I want to do this as it is something I am working on that is not related to current theories and would cause problems if I discussed it here.

Scaling numbers up can easily be done by using scientific notation.

But a Planck volume is not 1 m... I was thinking I could scale them up somehow to say make 1 Plank volume equal to 1 cubic metre for convenience and then derive the other units from that.

(If I understand your statement correctly.)

I think the idea was to divide it by 4x10^{-105} to make it easier to work with.

The problem is with h-bar if I have h at 1. If I have 1/2pi for h-bar then how would this relate to G and c? The units are no longer normalised, are they?

I think that is what I will have to do otherwise I am comparing apples with pears. Ultimately I want to convert mass to a volume. I need to factor in a density for a rest mass energy. I want to plot volume and mass for various elements at rest mass. Unless this has already been done. I also want to plot valency against specific gravity for elements in the periodic table. Does anyone know if this has been done somewhere.

And yes, you can certainly find tables of densities online. However, be aware that density is a macro phenomenon that depends on the arrangement of the atoms. There is not one single density for an element. This probably means that what you are seeking to do isn't possible.

Yes, if you don't want to deal with ugly values, working with equations can avoid that.

That's what I am thinking.

I know and that is going to be a real problem. I haven't worked out how to resolve it yet. I am sure there will be a way but the math will be complex. Maybe too complex.

This then leads on to the electromagnetic radius for any mass.

Has anyone heard of the scale invariant quantum Hall impedance.

I found this.

Since the OP is hijacking his own thread, it's a good time to stop.
