Units of energy Units of energy Because energy is defined via work, the SI unit for energy is the same as the unit of work – the joule (J), named in honor of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, 1 joule is equal to 1 newton metre and, in terms of SI base units An energy unit that is used in atomic physics, particle physics and high energy physics is the electronvolt (eV). One eV is equivalent to 1.60217653×10 J. In spectroscopy the unit cm = 0.000123986 eV is used to represent
UNIT to be some kind of covert counter-terrorist unit. Although the Brigadier originally states that UNIT do not arrest people, as of the 21st century, UNIT has the authority to detain persons indefinitely without trial, appeal, outside contact or legal representation, as experienced by Toshiko Sato before she was recruited to work for the British government by the Torchwood Institute in a flashback in the "Torchwood" episode "Fragments" (2008). The organisation was rearranged by Kate Stewart, the daughter of Brigadier Lethbridge-Stewart. In "The Power of Three" (2012), Kate heads UNIT's scientific research department, which now has authority over the military branch.
