Often used as a comparative power, where the tons referred to are tons of TNT. The "kiloton (of TNT)" is a unit of energy equal to 4.184 terajoules (4.184×1012 J). 1 Mt = 1000000000 kg. The bomb that fell on Hiroshima, ironically called Little Boy, produced an explosion of 15 kilotons (or the equivalent of 13,600 tonnes (15,000 US tons) worth of TNT… so megaton = million tons. As such, nuclear weapons are measured in kilotons (abbreviated kt, thousands of tons of TNT) or megatons (mt, millions of tons of TNT). One megaton of TNT explodes with an energy yield of about 4.18 x 10^15 joules, or about twice the energy of the Chelyabinsk meteor. The 'megaton (of TNT)' is a unit of energy equal to 4.184 petajoules. [9], So, one can state that a nuclear bomb has a yield of 15 kt (6.3×1013 J); but an actual explosion of a 15000 ton pile of TNT may yield (for example) 8×1013 J due to additional carbon/hydrocarbon oxidation not present with small open-air charges.[8]. 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 (see Bonus Factoids below)..

How well have you been paying attention this month? Similarly, a 1 megaton weapon would have the energy equivalent of 1 million tons of TNT. For example, if a timber-cutting formula calls for a charge of 1 kg of TNT, then based on octanitrocubane's RE factor of 2.38, it would take only 1.0/2.38 (or 0.42) kg of it to do the same job. TNT is yet another method for quantifying energy released, but this time the energy released during an explosion. [8], Such differences can be substantial. So we just take our 1000 kilotons and multiply by 1000 (I think) to have 1,000,000 kilotons. The time for the asteroid to impact the earth is (10,000 m)/(1 x 10 4 m/sec) = 1 sec. or 50 million megatons! A merger of two black holes, resulting in the, This page was last edited on 7 May 2021, at 04:34. Calculating a single RE factor for an explosive is, however, impossible. For TNT this has been accurately measured as 4686 J/g from a large sample of air blast experiments, and theoretically calculated to be 4853 J/g. The explosive yield of TNT is considered the standard measure for strength of … The "kiloton (of TNT)" is a unit of energy equal to 4.184 terajoules (4.184×10 J). The device tested in 1945 had a 20 kiloton yield, meaning it had the explosive force of 20,000 tons of TNT. One kiloton is 1,000 tons of TNT. Within 20 years, the US and USSR tested nuclear weapons larger than 10 megatons, or … Menu Definition: In relation to the base unit of [energy] => (joules), 1 Megatons Of TNT (MtTNT) is equal to 4.184E+15 joules, while 1 Joules (J) = 1 joules. So, an exaton of TNT is an energy of 4*10^15 * (10^18/10^6) = 4*10^15 * (10^12) = 4*10^27 J, … Megaton (noun). Later estimates for the Chicxulub impactor energy have climbed to between 300 million megatons and 11,900 million megatons. The explosive energy of a quantity of TNT the. Suppose one … megatons or tons The SI derived unit for energy is the joule. Under controlled conditions one kilogram of TNT can destroy (or even obliterate) a small vehicle. 1 Mt = 1000000000 kg. In evaluating the destructive power of a weapons system, it is customary to use the concept of equivalent megatons (EMT). Can you spell these 10 commonly misspelled words?
