List of orders of magnitude for energy; Factor (joules) SI prefix Value Item 10 −34: 6.626 × 10 −34 J: Energy of a photon with a frequency of 1 hertz. [1]8 × 10 −34 J: Average kinetic energy of translational motion of a molecule at the lowest temperature reached (38 picokelvin [2] as of 2021)
The joule (/ dʒ uː l / JOOL, or / dʒ aʊ l / JOWL; symbol: J) is the unit of energy in the International System of Units (SI). [1] In terms of SI base units, one joule corresponds to one kilogram-square metre per square second (1 J = 1 kg⋅m 2 ⋅s −2).
The "kiloton (of TNT equivalent)" is a unit of energy equal to 4.184 terajoules (4.184 × 10 12 J). [2] A kiloton of TNT can be visualized as a cube of TNT 8.46 metres (27.8 ft) on a side. The " megaton (of TNT equivalent)" is a unit of energy equal to 4.184 petajoules ( 4.184 × 10 15 J ).
Comparative fireball radii for a selection of nuclear weapons. [citation needed] Contrary to the image, which may depict the initial fireball radius, the maximum average fireball radius of Castle Bravo, a 15-megatonne yield surface burst, is 3.3 to 3.7 km (2.1 to 2.3 mi), [6] [7] and not the 1.42 km displayed in the image.
Gummies, chocolates, hard candies, and desserts like cookies, cakes, and pastries are sugar bombs that offer a quick energy boost followed by a crash — and not much else. Fried and fast foods.

The proportion of plus-size people in the UK is rising. The NHS says that the percentage of obese people almost doubled in a quarter-century from 15 per cent in 1997 to 29 per cent in 2022.
