Energy Conversion Calculator/n/nAn energy converter calculator. Select the units you wish to use and enter the value in the input units in the first text box. The result will be displayed in the second text box. /n/nConvert energy measurements between: Btu (th), Btu (mean), calories (IT), calories (th), calories (mean), calories (15C), calories (20C), calories (food), centigrade heat units, electron volts, ergs, foot-pound force, foot poundals, gigajoules, horsepower hours, inch-pound force, joules, kilocalories (IT), kilocalories (th), kilogram-force meters, kilojoules, kilowatt hours, megajoules, newton meters, therms, watt seconds, watt hours/n/nJoules to kJ conversion/nJoules to BTU conversion/nJoules to Calories conversion/nJoules to kcal conversion/nJoules to kWh conversion/nJoules to eV conversion/nkJ to Joules conversion/nkJ to BTU conversion/nkJ to calories conversion/nkJ to kcal conversion/nBTU to kJ conversion/nBTU to Joules conversion/nBTU to kWh conversion/nkWh to BTU conversion/nkWh to Joules conversion/nCalories to Joules conversion/nCalories to kJ conversion/nCalories to kcal conversion/nkcal to calories conversion/nkcal to joules conversion/nkcal to kJ conversion/neV to joules conversion/neV to keV conversion/neV to MeV conversion/neV to GeV conversion/nkeV to eV conversion/nMeV to eV conversion/nGeV to eV conversion/n/nThe SI unit of energy rate (energy per unit time) is the watt, which is a joule per second. Thus, one joule is one watt-second, and 3600 joules equal one watt-hour. The CGS energy unit is the erg and the imperial and US customary unit is the foot pound. Other energy units such as the electronvolt, food calorie or thermodynamic kcal (based on the temperature change of water in a heating process), and BTU are used in specific areas of science and commerce.
