This is a “Follow on” rendering of a recent blurb on the subject of alternatives to Albert’s formula.
(Quite confusing stuff to understand I guess.)
However, sometimes that is part of the price that we have to pay for progressiveness in our correlation of fragmented scientific, or worldly related facts.

Albert Einstein‘s famous formula for energy is, E = MC2.

Another formula that quite possibly matches this in all respects as to incomings and outgoings is,
V = MC2. (Where V = Voltage.) (However, mind you, V can also = Vacuum.)
Giving a formula of, V, or V, = E = MC2.

It can also stay exactly as Albert wrote it, E = MC2

But in this case, we can change it to, E = Electric.
And in addition, make M = Magnetic.
Moreover, of course, this formula is reversible too.
But with one essential difference, E = M-C2
The above says–Electricity equals Magnetism, minus the speed of light Squared. (multiplied by itself.)
Also if we make, M = A, for Amperage–(For the mass of the current.) We finish up with another formula of V = AC2
And the reverse of this formula is, A = V-C2

The difference between these formulas is that Albert’s only mentions “E”, as the constant for energy.
Whereas these other formulas give the alternatives to “E” or “M”.

FOR YOUR REFERENCE

Another use for Albert’s famous formula. E = MC2.

With In the exercise outlined below is the means to take a non-prejudicial obverse observation of Albert Einstein’s famous formula. This formula tells us the sum total amount of energy that would be produced, if a lump of something that has mass, (read body), would be equivalent to if it was suddenly all converted into energy.

The Legend of this formula states that:

E – symbolizes the amount of units of Energy produced.
M – symbolizes the amount of units of Mass used to produce this energy.
C – symbolizes using the fixed speed of light.
Which is, 186,000 miles per second or, 300,000 kilometers per second for the multiplication purpose? This is required as the Constant reference benchmark point for the calculation.
(The C is taken from the Latin word Celeritas, which means speed.)

The subscripted 2 denotes Squared which is the multiplication factor of C that is to be applied to M.
(Squared = Multiplied by itself.)

This all means that to calculate the amount of energy obtainable, you multiply the Mass, by the Square of the Speed of light.

That is C = 300,000 x 300,000= (You can work this out for yourself if necessary)
This calculation gives the multiplication factor required.
You then multiply the amount of Mass by this figure.

E=mc2 – Energy = Mass, Multiplied by the speed of Light, Squared.
