> 12.5 kilotons TNT / (6 years + 9 months) -> horsepower

At first I thought that this is some peculiar quality of bizarre american unit system that energy released by kiloton of TNT divided by one month equals power of one horse. As opposed to usual joules, seconds and watts.

Amazing how fast you can do "back of the envelope" calculations with such tool empowered by default with unit conversions.




You can do exactly the same thing sans frink with google, except you have to look up the KT --> J conversion yourself (google is still missing some obscure units).

Just stick in:

12.5*4.184e12 J / (6 years + 9 months) in hp


WolframAplpha is also useful for those kind of calculations (couldn’t find a way to do the last one, though): http://www.wolframalpha.com/input/?i=12.5+kilotons+TNT+%2F+%...
