...megatonnes, I think. Yep megatonnes. Apparently the theoretical maximum yield-to-weight ratio for fusion weapons (thermonuclear) is 6 megatons of TNT per metric ton of bomb mass (25 TJ/kg) ^_^

Ever heard of the Tsar Bomba? USSR, most powerful nuclear weapon ever detonated, yield of 50 megatons, (50 million tons of tnt). In its "full" form (i.e. with a depleted uranium tamper instead of one made of lead) it would have been 100 megatonnes of TNT (420 PJ).

I think when I did some research on Thermonuclear weapons the search engine was limiting to bombs detonated by America and biased on the highest yield to weight ratio weapons. The EC17/Mk-17, the EC24/Mk-24, and the B41 (Mk-41). 25 megatonnes of TNT (100 PJ) 20 short tons (18,000 kg) with a mass of 4800 kg and yield of 25 Mt. However this was biased on 1950's weaponry so its comforting that Thermonuclear technology has come a long way since than. The USSR definitely wins hands down in the WOMD arms race I think.
