Table of coefficients for energy unit conversion between atomic unit (hartree), joule (J), electron volt (eV), cm-1, kJ/mol, and kcal/mol.
Type in the amount you want to convert and press the Convert button. Joules to Kilocalories. Convert between the units (J → kcal) or see the conversion table.
The international table (IT) calorte (generatfy preferred by engineers) IS exactly 4.1868 J by definition and corresponds to the specific heat of water at 150C. The thermochemcal calorie (generally preferred by physicists) ts exactly 4.184 J by definition and corresponds to the specific heat of water at room temperature.

Energy converter tool adapted from Colby College. Enter your energy value in the box with the appropriate units, then press "tab" or click outside of the input box. Hartrees (Eh)
To get the energy for one molecule, divide kJ/mol by Avogadro's number, 6.022 x 10 23. Kilocalories per mole (kcal/mol) A calorie was originally defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius. One calorie = 4.184 J. One kcal = 1,000 cal. Nanometer(nm)
