A kiloton of TNT can be visualized as a cube of TNT 8.46 metres (27.8 ft) on a side. The "megaton (of TNT equivalent)" is a unit of energy equal to 4.184 petajoules (4.184 × 10 15 J). [3] The kiloton and megaton of TNT equivalent have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon.

The energy of various amounts of the explosive TNT (kiloton, megaton, gigaton) is often used as a unit of explosion energy, and sometimes of asteroid impacts and violent explosive volcanic eruptions. One ton of TNT produces 4.184 × 10 9 joules, or (by arbitrary definition) exactly 10 9 thermochemical calories (approximately 3.964 × 10 6 BTU ...

An equivalent (symbol: officially equiv; [1] unofficially but often Eq [2]) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. It is an archaic quantity that was used in chemistry and the biological sciences (see Equivalent weight § In ...
In the TNT article, there is a line, "The explosive energy utilized by NIST is 4184 J/g (4.184 MJ/kg).[16]", which probably means to say that TNT has an explosive yield of 4.184 MH/kg, making for a probable third value, but the statement is ambiguous: On first read, I thought that NIST was an explosive that produced 4.184 MJ of explosive energy ...
It is accurate to within an order of magnitude to say that 10 44 J is equivalent to 10 28 megatons of TNT equivalent. However, it is wrong to say that such an amount of TNT would have a mass a mere 1⅔ the mass of the earth. 10 28 megatons is 10 37 kilograms. The earth has a mass of 5.9735*10 24 kilograms.
TNT is valued partly because of its insensitivity to shock and friction, with reduced risk of accidental detonation compared to more sensitive explosives such as nitroglycerin. TNT melts at 80 °C (176 °F), far below the temperature at which it will spontaneously detonate, allowing it to be poured or safely combined with other explosives.
