About calorie
The calorie (thermochemical) is a unit of energy equal to 4.184 joules (1 cal = 4.184 J), the SI derived unit of energy.
The calorie (thermochemical) is also equal to 0.004184 kilojoules (kJ), or 0.001 kilocalories (thermochemical) (kcal), or 10-9 gigacalories (thermochemical) (Gcal), or 0.003965667 British thermal units (IT) (BTU), or 0.002203148 Celsius heat units (IT) (CHU), or 0.00116222222 watt hours (Wh) or 1.16222222 × 10-6 kilowatt hours (kWh).
The calorie is the energy required to increase the temperature of one gram of water by one degree Celsius (1.8 degrees Fahrenheit) at a constant pressure of one atmosphere.
