The old calc for this vanished for some reason...thankfully, I had it saved to Gdocs, so I can repost it here.

King Kittan's sacrifice shakes the entire galaxy. Looking back at my old Noo shake the Universe calc for help. First, the energy to shake one planet noticably enough to be felt, or at least magnitude 2.5, though the highest I could get by playing around with the impact calculator was magnitude 2.3, which results in 3.72 X 10^12 Joules. Next we need the area that get's shook. Divide that by 10,000 and you have 372000000 joules The radius of the Milky Way is 52,850 lightyears, or 3720000000000 joules of seismic energy.
I = S/4pa
372000000 = S/(4 X π X 4.99988926e20^2)
S = 372000000 X (4 X π X 4.99988926e20^2)
= 1.1686207e51/10^44
= 11.686207 MEGAFOE
Final Result
Kittan's final sacrifice = 11.686 MEGAFOE
(I've checked with a friend and this is an accurate translation.)
