===Energy===
* A ton of [[TNT equivalent]], and its multiples the kiloton, the megaton, and the gigaton. Often used in stating the power of very energetic events such as [[explosion]]s and [[volcanic]] events and [[earthquakes]] and [[asteroid]] impacts. A [[gram]] of TNT as a unit of [[energy]] has been defined as 1000 thermochemical calories ({{convert|1000|cal|J|0|abbr=on|lk=on|disp=or}}).
* The [[Little Boy|atom bomb dropped on Hiroshima]]. Its energy yield is often used in the [[public media]] and popular [[books]] as a unit of energy. (Its yield was roughly 13 kilotons, or 60 TJ.)
* One stick of [[dynamite]].
