Your math is off.

21,000 lbs of TNT is 10.5 tons. That's 0.015 kilotons.

Sorry, but I disagree (I pick 1/2 kiloton out of air, that is why the question mark). The bomb weighs 21,000 lbs, but doesn't use TNT to generate its explosive force. It disperses gases than ignites them. My question: Is the total explosive power greater than it's TNT weight? I would think so. But how much greater was the question.
