What is calorie (IT)?


The calorie (IT) is a unit of energy equal to 4.1868 joules (1 cal = 4.1868 J), the SI derived unit of energy. It is also equal to 0.0041868 kilojoules (kJ), or 4.1868x10-6 megajoules (MJ), or 4.1868x10-9 gigajoules (GJ), or 0.0039683207 British thermal units (IT) (BTU), or 0.0022046226 Celsius heat units (IT) (CHU), or 0.001163 watt hours (Wh) or 1.163x10-6 kilowatt hours (kWh).

The calorie is the energy required to increase the temperature of one gram of water by one degree Celsius (or 1.8 degrees Fahrenheit) at a constant pressure of one atmosphere.

The calorie definition varies as follows:

  • The calorie (thermochemical) (cal) is equal to 4.184 joules (J)
  • The calorie (IT) (cal) is equal to 4.1868 joules (J)
  • The calorie (mean) (cal) is equal to about 4.19002 joules (J)
  • The calorie (4 °C) (cal) is equal to about 4.2045 joules (J)
  • The calorie (15 °C) (cal) is equal to 4.1855 joules (J)
  • The calorie (20 °C) (cal) is equal to about 4.1819 joules (J)

(i) The SI is an abbreviation for the International System of Units
(ii) The IT is an abbreviation for the International [Steam] Table
(iii) The food calorie - used in nutritional contexts only - is equal to 4.184 kilojoules or 1,000 thermochemical calories. The food calorie is also referred to as kilocalorie on the nutrition labels.
