Yes. What has that to do with my point above?

I meant that E is a symbol used for energy in equations.

How on earth does that follow?

And that?

E = m c^2 is an equation saying that the expression m c^2
is an energy.

Sorry, you still seem to use standard words with rather
strange meanings.

It is.

There is.

You seem to be deeply confused about the relationship between
mathematical equations describing the world and the world
itself.

Who has ever stated that E is the unit of energy, and why
is that relevant?
Bye,
