E=Mc² is a lot!

I’ve been thinking about Einstein’s E=mc²

Presume 1Kg wood (m)
Presume c = 299 792 458 metres per second
Therefore c² = 89875517873681760 m/s (v)
E=mc² = 1 x c² = c².

Convert to joules of energy (KE = 0.5m X v²)
KE = 4.0388043565312E+33 J
KE = 4038804356531200000000000000000000 J

Convert J to TNT equivalent.
9.6529740834876E+23 Tons Of TNT
965 297 408 348 760 000 000 000 Tons Of TNT (!)

as words…
nine hundred sixty-five sextillion two hundred ninety-seven quintillion four hundred eight quadrillion three hundred forty-eight trillion seven hundred sixty billion Tons Of TNT.

Moral of the Story: NEVER use wood in your fireplace!

Cheers.
