So destroying the Himalayas........
Himalayas = 161932476090 metric tons
Speed of light = 299 792 458 m/s
161932476090 x 299792458^2 = approx. 1.46 x 10^28
(1.46 x 10^28)/2 = approx. 7.28 x 10^27
Attack Potency Chart (Stolen from VSBW)
assuming 7.28 x 10^27 is in joules
then 5A.
My math is messed up.
So I assumed this was Godzilla destroyed this by converting it to energy.
So don't completely trust this. I really need mathematcians to help me.
