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
Office of Scientific and Technical Information Office of Scientific and Technical Information The Office of Scientific and Technical Information (OSTI) is a component of the Office of Science within the U.S. Department of Energy (DOE). The "Energy Policy Act" PL 109-58, Section 982, called out the responsibility of OSTI: "The Secretary, through the Office of Scientific and Technical Information, shall maintain with the Department publicly available collections of scientific and technical information resulting from research, development, demonstration, and commercial applications activities supported by the Department." OSTI provides access to energy, science, and technology information through publicly available web-based systems, with supporting tools and technologies to enable
