Little Boy weighed 4.85 tons and had an explosive yield of about 15 kilotons TNT equivalent.If you really want Little Boy's weight expressed in kilotons it was 0.00485 kilotons.
Using E=mc2 2g of antimatter will yield the equivelent of 42.962 kilotons of TNT.
Little Boy had a yield of fourteen kilotons; the EQUIVALENT of 14,000 tons of TNT. Of course, no single bomber then or today could carry that much TNT, but the use of atomic reaction allowed for a bomb of similar destructive capability.Little Boy had no TNT in it at all. The chemical explosive used to assemble the uranium was cordite, ordinary smokeless powder.
Kilotons are used to measure the power of atomic bombs. A kiloton is the power equivalent of 1000 tons of TNT, a chemical explosive used in bombs. A 15 kiloton atomic bomb has the power of 15,000 tons of TNT.
An average nuclear weapon can have explosive power ranging from tens of kilotons to hundreds of kilotons of TNT equivalent. For comparison, the bomb dropped on Hiroshima in 1945 had an explosive power of around 15 kilotons.
At various times it has been estimated anywhere from about 12 kilotons to 20 kilotons, I believe the most accurate current estimate is about 13 kilotons.
See the related link for answer. A 5 is 32 kilotons of TNT, a 6 is 1 megaton of TNT.
The force released by a nuclear bomb is typically measured in kilotons or megatons of TNT. For example, the atomic bomb dropped on Hiroshima released an energy equivalent to approximately 15 kilotons of TNT. The force generated from a nuclear explosion is determined by the size and type of the bomb.
A 1 kiloton nuclear blast has the equivalent explosive force of detonating 1 kilotons of TNT.
The size of a nuclear explosion can vary depending on the yield of the weapon. The explosions can range from several kilotons (thousands of tons of TNT) to megatons (millions of tons of TNT) of explosive power.
21 kilotons is about 46,297,075.06 pounds.
The "Fat Man" atomic bomb, dropped on Nagasaki, Japan, on August 9, 1945, had a yield of approximately 21 kilotons of TNT. This means that its explosive power was equivalent to that of 21,000 tons of TNT. The bomb's design utilized plutonium-239 and was part of the Manhattan Project during World War II.
