About Calorie (thermochemical) (cal)
The small calorie (cal) is the energy needed to raise one gram of water by one degree Celsius at standard pressure. While largely replaced by the joule in scientific contexts (1 cal = 4.184 J exactly), the calorie remains in use in chemistry and is the basis for the food Calorie (kilocalorie).
About Joule (J)
The SI derived unit of energy, one joule equals the work done by a force of one newton moving an object one meter. Named after James Prescott Joule, who demonstrated the mechanical equivalent of heat, the joule is used in physics, chemistry, and engineering for all forms of energy, work, and heat.
