  2. TNT equivalent - Wikipedia

    en.wikipedia.org/wiki/TNT_equivalent

    TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules ( 1 gigacalorie ), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.

  3. kT (energy) - Wikipedia

    en.wikipedia.org/wiki/KT_(energy)

    kT (also written as k B T) is the product of the Boltzmann constant, k (or k B), and the temperature, T.This product is used in physics as a scale factor for energy values in molecular-scale systems (sometimes it is used as a unit of energy), as the rates and frequencies of many processes and phenomena depend not on their energy alone, but on the ratio of that energy and kT, that is, on ⁠ E ...

    Kaituozhe-1. Kaituozhe-1 ( KT-1) was small, solid fueled launch vehicle based on the road mobile DF-21 IRBM with an additional upper stage (in total 4 stages [1] ). It was 13.6 meters in length and 1.4 meters in diameter, with launch mass of 20t. It was possible to launch KT-1 both from a truck-based platform or from airborne platform. [1]

  6. Nuclear weapon yield - Wikipedia

    en.wikipedia.org/wiki/Nuclear_weapon_yield

    Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...

  7. Fineness - Wikipedia

    en.wikipedia.org/wiki/Fineness

    It is an extension of the older karat system of denoting the purity of gold by fractions of 24, such as "18 karat" for an alloy with 75% (18 parts per 24) pure gold by mass. The millesimal fineness is usually rounded to a three figure number, particularly where used as a hallmark , and the fineness may vary slightly from the traditional ...
