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
Department of Scientific and Industrial Research (United Kingdom) purposes. Large areas of research were the responsibility of other bodies - aviation, atomic energy, agriculture, health and medicine, meteorology - though it might undertake specific investigation on behalf of the responsible departments. The department encouraged and supported scientific research in universities and other institutions by means of grants for special research projects, research fellowships, studentships, grants to research associations and research contracts. The department absorbed or created a number of research organisations, which included large laboratories for special fields of work. Existing institutions for which it assumed responsibility were the National Physical Laboratory from the Royal Society in 1918,
