“releasing more energy than 10 billion atomic bombs.”
Haden’t realised that “atomic bomb” was a measure of energy. How many BTUs is it?
See this amazing image:
******************************
"atomic bomb" is a unit of energy known only to journalists.
About 1200 hogsheads of mead worth...
I always use the estimate that a kiloton of TNT ~= 10^12 Joules. Close enough for atom bombs, I always felt.
The actual number is about 4.2 x 10^12 Joules. You can take it from there for conversions.
Well, one kiloton = 3,965,666,831.39 BTUs So... if their unit of measurement is one Hiroshima... we have to figure kilotons:
One kiloton = 3,965,666,831.39 BTUs
3,965,666,831.39 BTUs x 15 x 10,000,000,000 = 5.948500247085e+20BTUs = 594,850,024,708,500,000,000 BTUs or so...
Call it 595 Quintillion BTUs
However, if unit is a Tsar Bomba then we need to figure on megatons
One megaton = 39,656,668,313,900 BTUs.
Assuming the yield of the Twar Bomba unit was only 55 Megatons, then the calculation would be:
39,656,668,313,900 BTUs x 55 X 10,000,000,000 = 2.181116757264e+25 BTUs = 21,811,167,572,640,000,000,000,000 BTUs
Call that one 21.8 Septillion BTUs.
Does that answer your question???
