TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. A ton of TNT equivalent is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie). [1] It is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of trinitrotoluene (TNT).
The energy of various amounts of the explosive TNT (kiloton, megaton, gigaton) is often used as a unit of explosion energy, and sometimes of asteroid impacts and violent explosive volcanic eruptions. One ton of TNT produces 4.184 × 10 9 joules, or (by arbitrary definition) exactly 10 9 thermochemical calories (approximately 3.964 × 10 6 BTU ...
Other smaller tests include Air Vent I and Flat Top I-III series of 20 tons TNT at Nevada Test Site in 1963–64, Pre Mine Throw and Mine Throw in 1970–1974, Mixed Company 1 & 2 of 20 tons TNT, Middle Gust I-V series of 20 or 100 tons TNT in the early 1970s, Pre Dice Throw and Pre Dice Throw II in 1975, Pre-Direct Course in 1982, SHIST in ...
In 2023, total world crude steel production was nearly 1.9 billion tons . The biggest steel producing country is currently China, which accounted for 54% of world steel production in 2023. [1] In 2020, despite the COVID-19 pandemic, China became the first country to produce over one billion tons of steel. [2]
NBC is preparing a $2.5 billion bid, ... BofA says TNT “earns by far the highest affiliate fee of all [WBD’s] cable networks” with an estimated $3 per subscriber. It would be unlikely to ...
It released the equivalent energy of roughly 2.9 kilotons of TNT (12 TJ). [ 2 ] Mont-Blanc was under orders from the French government to carry her cargo from New York City via Halifax to Bordeaux , France.
The first two explosions at the facility, which is located in the Binhai New Area of Tianjin, happened within 30 seconds of each other; the second explosion was larger and involved the detonation of approximately 800 tons of ammonium nitrate (equivalent to about 256 tons of TNT). Fires caused by the initial explosions continued to burn ...
