Calorie Conversion / Calorific Value Conversions

However, in many countries it remains in common use as a unit of food energy. The kilocalorie per mole remains in use in computational chemistry and molecular spectroscopy.
Definitions vary but are all based on the specific heat capacity of water. The gram calorie, approximately 4.2 J, is based on one gram of water. The kilogram calorie, equal to one thousand gram calories, is based on one kilogram of water. In the context of nutrition, and especially food
labelling, a larger unit is used and referred to interchangeably by the terms calorie (or Calorie) and kilocalorie.

The calorie is a pre-SI metric unit of energy. In most fields its use is archaic, having been replaced by the SI unit of energy, the joule. Historically, the calorie has had two major alternative definitions differing by a factor of one thousand. In addition to these two major alternative
definitions, minor variants of the definition of this unit also exist differing in the exact experimental conditions used, most notably the start temperature of the water.

- Red meat (eg. beef, lamb, veal): 264 Cal, 1106 Kj
- Poultry: (eg. chicken, turkey, duck, goose): 253 Cal, 1058 Kj
- Seafood - Fish: 163 Calories, 681 Kilojoules
- Seafod - Crustaceans & Mollusks: 141 Cal, 590 Kj
- Game Meat (eg. Kangaroo, Rabbit): 144 Cal, 603 Kj
- Eggs: 170 kcal, 710 Kilojule
