Today I found out that one Calorie is equivalent to one gram of
TNT in terms of energy. First of all, lets clarify what is one
calorie means. A Calorie is the amount of energy required to
raise the temperature of one kilogram of water by one degree
Celsius. One Calorie is also approximately 4.184 kilojoules or
about 1.16 watt/hours. TNT (Trinitrotoluene), is a chemical
compound. This yellow-colored solid is sometimes used as a
reagent in chemical synthesis, but it is best known as a useful
explosive material with convenient handling properties. The
explosive yield of TNT is considered to be the standard measure
of strength of bombs and other explosives. Unlike a Calorie
though, TNT is also an actual thing, namely Trinitrotoluene,
which is a yellow colored substance that has some interesting
properties for an explosive. The explosive yield of TNT is
considered the standard measure for strength of bombs and other
explosives with 1 ton of TNT equaling 4.184 gigajoules. So 1 kg
of TNT then equals 4.6 megajoules,
