The value of mc^2 is in joules (energy). The value of hf is in joules (energy). You need to understand dimensional analysis to appreciate this.
Alan Calverd: .It's more fun to shout than to learn, and being wrong isn't wrong these days, just "alt".
Boring Chemist: What you have described as an "error" has been experimentally verified as the truth. Also, it has the advantage that the maths works- whereas the thread title's maths doesn't work.
This is unlike the real question in the OP which is whether Louis De Broglie's postulate that mc2 = h x frequency actually makes sense, according to you it does, despite the fact that the two formula do not match up in any way at all, mathematically it is ludicrous to compare a solid with a wave. Just face it that's common sense.
It would be even more interesting to be told why our stuff actually works.

Burning sodium creates a wavelength. A photograph can have a negative.
I found it to be a good tool in analytical chemistry. So its useful for what absorbs and what does not.
HPLC, SFC, IR. We are discussing wavelengths. Useful in analytical chemistry.Main stream theory of wavelengths changing as they travel through different gravity potentials has a math basis but so does wavelengths staying the same while the gradient dilation of the energy state changing the calibration of the instrument cell length to reading. Take the fixed sodium wavelength, the calibration will always read the same wavelength in every frame. This is similar to measuring the same speed of light in every frame. It depends on where the wavelength is created and where it is detected that will read the same or different wave shift. Each different gradient position has a different measuring stick. So you create the light in one dilation and measure it in another dilation there will be a measured shift in wavelength while the wavelength remained the same. This is the same reason the speed of light is measured the same in every frame of SR and GR. In SR the geometry of the finite speed of light increases the length of view in a measuring stick with light. Visual only. GR dilation of the electron path increases the relative size of your measuring stick. A physical change. They are equivalent for distance of light per volume of energy state density.What moves the electron? Energy moves the electron. e path + dilation = E pathWhen mass reaches the speed of light on the surface of a sun the dilation exceeds the energy of space and all of the atoms compress into a BH where space between the atoms no longer exists. The volume of our sun would compress to about 1.7 miles in diameter.
Alan Calverd : It's interesting to be told that we are all wrong, especially by a bloke who doesn't know the difference between velocity and acceleration. "Out of the mouths of babes", perhaps?
McQueen : On the left side, a stands for acceleration, which has units of length divided by time squared.
McQueen: E is not equal to force x displacement (as claimed by Alan Calverd nuclear physicist!) , it is W = F x s (Work = force x distance ) and E = Fa : Energy = Force x velocity / time .

Bored Chemist : Common sense is wrong.

Impyre ; If F=ma and E=mc^2, it seems apparent that F and E aren't the same thing. It sounds in your post as if you're disputing something that noone ever said was a thing to begin with. I don't think anyone else thinks F=E, who are you trying to convince?
McQueen: It is not possible to compare a solid with a wave and then to generalise that all matter has corresponding waves. I can see that you are already highly sceptical but think about this:Louis de broglie equated the energy equations of planck and einstein:E= mc2 ; E = hfm is the moving mass of the particle, for a photon the rest mass is zero( or very nearly]so it does not undergo relativistic variation of mass .Hence mass energy equivalence for the photon becomes meaningless. From this it follows that it is impossible to equate the two equations Looked at from another view point: Here E=hf does not give the energy of electron. It gives the energy required / released when electrons change their energy levels. How then is it possible if E = hf applies to a change of energy in an electron for E = hf to equal E = mc2 ? hf = mc2From the above it follows that f = mc2/h Suppose an electron with a mass of 9.1 x 10-31 Kg Then its frequency ( in the context of its energy should be ( 9.1 x 10-31 x 9 x1016 / 6.63 x 10 -34 J/s) what does this mean if anything ? Ans = 7.76x1021 Hz. So apart from everything else electrons have an intrinsic frequency of around 10,000,000 THz ! wow!You could go on: If the velocity of the De Broglie wave is VB and the velocity of the particle is VP then VB x VP = c 2.Presumably if the two velocities are multiplied the result is the speed of light squared? What an amazing relation......... Do you still advise unquestioning obedience by myself and everyone else in this New Theories forum and to insist that we should be satisfied that the De Broglie hypotheses has been verified! Further since VB x VP = c 2 .VP < c and VB > c. The velocity of the De Broglie wave will always be faster than the speed of light, change with the velocity of the particle AND the Velocity of the matter wave changes. What kind of wave is this? It has totally unacceptable wave properties. Is it a probability wave that has a dual existence? One existence in probability and another ( when necessary) in reality?
As I have said before the De Broglie relation is the last resort of scientists who had no other recourse.
