If the rule is personal preference then my personal preference is simply to acknowledge that the quantities have different dimensions in...

Not sure if I understand your question. The fact that photons gives a null for the Minkowski metric does not mean everything must follow...

Yes, but would you perhaps agree that it provides a clearer understanding of what is going on than to just say ##c=1##? In the latter...

Oh my goodness! What a mess! :-) I guess all quantities had to change to accommodate the ##k##. Yes, such scenarios are also possible...

Interesting example. I agree that the two ways to see the conversion is effectively equivalent. However, I still prefer to think of it...

So ##k## is dimensionless. It does not affect the units.

What I meant was that the process of making ##c## dimensionless is to absorb it into another quantity. The reason is that the...

Basically, but with the important caveat that there are no magnetic monopoles. See the rest of the quoted message.

When comparing systems of equations in different systems of units, one should be able to trace such quantities to understand why they...

Would you agree that what it actually implies is that ##c## is being absorbed into the time coordinate?

But the constant speed-of-light ##c## is "dimensional" only because we humans have traditionally chosen to measure length and time in...

Perhaps, to clarify one should add that if one quantity is changed by a given factor, then another quantity must be change by the...

This is a much better question, and is getting close to the type of thing that you have to do in order to understand how important the...

The Casimir Effect is related to Van der Waals forces: http://thphys.irb.hr/wiki/main/images/2/2c/Casimir.pdf Thanks Bill

Strictly speaking, the reason why such quantities "disappear" is because they are absorbed into other quantities. A change in units does...
