Electron Volt -- from Eric Weisstein
An energy unit that is used in atomic physics, particle physics and high energy physics is the electronvolt (eV). One eV is equivalent to 1.602 176 634 × 10−19 J. [1] In spectroscopy the unit cm −1 ≈ 0.000 123 9842 eV is used to represent energy since energy is inversely proportional to wavelength from the equation . See more Energy is defined via work, so the SI unit of energy is the same as the unit of work – the joule (J), named in honour of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental … See more A unit of electrical energy, particularly for utility bills, is the kilowatt-hour (kWh); one kilowatt-hour is equivalent to 3.6 megajoule. … See more The calorie is defined as the amount of thermal energy necessary to raise the temperature of one gram of water by 1 Celsius degree, from a temperature of 14.5 °C, at a See more In spectroscopy and related fields it is common to measure energy levels in units of reciprocal centimetres. These units (cm ) are strictly … See more The British imperial units and U.S. customary units for both energy and work include the foot-pound force (1.3558 J), the British thermal unit (BTU) which has various values in the region of 1055 J, the horsepower-hour (2.6845 MJ), and the gasoline gallon equivalent See more Natural gas is often sold in units of energy content or by volume. Common units for selling by energy content are joules or therms. … See more In physics and chemistry, it is common to measure energy on the atomic scale in the non-SI, but convenient, units electronvolts (eV). 1 eV is equivalent to the kinetic energy acquired by … See more WebSep 4, 2007 · By 2006, renewable-energy consumption - hydro, biomass, geothermal, solar and wind - dropped to 6.9 percent of the total.
