Calculating a single RE factor for an explosive is, however, impossible. *: TBX (thermobaric explosives) or EBX (enhanced blast explosives), in a small, confined space, may have over twice the power of destruction. The "megaton (of TNT)" is a unit of energy equal to 4.184 petajoules (4.184 × 10 15 J). These complications have been sidestepped by convention. Naturally, this unit ignores effects beyond simple blast, effects such as heat and radiation. 3 megatons to tons = 3000000 tons. 4 megatons to tons = 4000000 tons. 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. English Language Learners Definition of megaton. The total solar irradience energy received by Earth in the upper atmosphere per hour. Moscow built a 100-megaton bomb called the TSAR BOMBA (“King of Bombs” officially the RDS-220), tested the day before Halloween, on October 30, 1961. so megaton = million tons. Menu For scale, these weapons were at least 500 times as strong as the first atomic bomb. 1 x 4.184E+15 J = 4.184E+15 Joules. Yields of nuclear explosions can be very hard to calculate, even using numbers as rough as in the kiloton or megaton range (much less down to the resolution of individual terajoules). A metric ton is exactly 1000 kilograms (SI base unit) making a megatonne equal to 1000000000 kilograms. The relative effectiveness factor (RE factor) relates an explosive's demolition power to that of TNT, in units of the TNT equivalent/kg (TNTe/kg). MegaTon of TNT to Attojoule. Always check the results; rounding errors may occur. The total power of aluminized mixtures strictly depends on the condition of explosions. The 'kiloton (of TNT)' is a unit of energy equal to 4.184 terajoules. 0.001 Mt Conversion base : 1 kT = 0.001 Mt. 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. 1. (Ancient meteorite or comet impacts may have significantly altered Earth's climate and contributed to the extinction of the dinosaurs and other life-forms.) So, the Hiroshima bomb was about 20kt. Hydrogen bombs of more than 50 megatons have been detonated, but the explosive power of the weapons mounted on strategic missiles usually ranges from 100 kilotons to 1.5 megatons. The device tested in 1945 had a 20 kiloton yield, meaning it had the explosive force of 20,000 tons of TNT. A kiloton of TNT can be visualized as a cube of TNT 8.46 metres (27.8 ft) on a side.

The energy contained in one megaton of TNT (4.2 PJ) is enough to power the average American household for 103,000 years. Small TNT explosions, especially in the open, don't tend to burn the carbon-particle and hydrocarbon products of the explosion. Unfortunately, Russia’s 100-megaton doomsday bomb is real. As such, nuclear weapons are measured in kilotons (abbreviated kt, thousands of tons of TNT) or megatons (mt, millions of tons of TNT). For safety purposes a range as wide as 2673–6702 J has been stated for a gram of TNT upon explosion. 1 megatons to tons = 1000000 tons. Later estimates for the Chicxulub impactor energy have climbed to between 300 million megatons and 11,900 million megatons. A metric ton is exactly 1000 kilograms (SI base unit) making a megatonne equal to 1000000000 kilograms. kilotonne TNT . MegaTon of TNT to Barrel of oil equivalent. or 50 million megatons! Even under very controlled conditions, precise yields can be very hard to determine, and for less controlled conditions the margins of error can be quite large. gigajoule (GJ) megajoule (MJ) kilojoule (kJ) One kiloton is 1,000 tons of TNT.
