gram calories) per one mole of substance. The unit symbol is written kcal/mol or kcal⋅mol−1. As typically measured, one kcal/mol represents a temperature
enthalpy of reaction in units of kJ·mol−1. Other units sometimes used to describe reaction energetics are kilocalories per mole (kcal·mol−1), electron volts
expressed in units of coulombs per mole (C/mol). As such, it represents the "molar elementary charge", that is, the electric charge of one mole of elementary
(Cal/g or kcal/g), mostly in food-related topics, and watt hours per kilogram in the field of batteries. In some countries the Imperial unit BTU per pound
