C = 186,000 miles / second
C^2 = 186,000 miles / second * 186,000 / second
C^2 = 34,596,000,000 miles / second^2

Oh, dear. What happened to the "miles" unit on the second factor of "C"? Shouldn't the units be "miles^2/second^2"?

Well, it was a good try anyway.

I have no idea what "miles^2 / second / second" means. Einstein must have though cause its in there.
