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 Megajoule (MJ)
One million joules, the megajoule is used for expressing the energy content of fuels and industrial energy consumption. One liter of gasoline contains about 34 MJ of chemical energy, and industrial boiler outputs and building energy audits often use megajoules as the standard unit.
