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
Information Bridge: Department of Energy Scientific and Technical Information Information Bridge: Department of Energy Scientific and Technical Information The Information Bridge: Department of Energy Scientific and Technical Information database provides free public access to over 298,000 full-text electronic documents of Department of Energy (DOE) research report literature. See list of academic databases and search engines. The documents are primarily from 1991 forward and were produced by DOE, the DOE contractor community, and/or DOE grantees. Legacy documents are added as they become available in electronic format.
