Force = [ mass x length / time2 ]

Energy = [ force x length ] = [ mass x length / time2 ] x [ length ] = [ mass x length2 / time2 ]

Mass = [ mass ]

c2 = [ length2 / time2 ]

The equation proposes that

Energy = [ mass ] x [ c2 ] .

From the dimensions above,

[ mass x length2 / time2 ] ?=? [ mass ] x [ length2 / time2 ]

The dimensional equivalence is right there, with no further fiddling.
