How many tons of TNT does a megaton represent
Unit of measurement some unit values occur naturally in science. Systems of units based on these are called natural units. Similar to natural units, atomic units (au) are a convenient system of units of measurement used in atomic physics. Also a great number of unusual and non-standard units may be encountered. These may include the solar mass (), the megaton (the energy released by detonating one million tons of trinitrotoluene, TNT) and the electronvolt. To reduce the incidence of retail fraud, many national statutes have standard definitions of weights and measures that may be used (hence "statute measure"), and these are verified by
TNT equivalent as dynamite contain more energy. The "kiloton (of TNT)" is a unit of energy equal to 4.184 terajoules. The "megaton (of TNT)" is a unit of energy equal to 4.184 petajoules. The kiloton and megaton of TNT have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon. The TNT equivalent appears in various nuclear weapon control treaties, and has been used to characterize the energy released in such other highly destructive events as an asteroid impact. A gram of TNT releases 2673–6702 J (joules) upon explosion. The energy liberated by one gram
