Definition:Large Calorie

Definition
The large calorie is a CGS unit of heat energy.

It was originally defined as equal to the energy required to raise the temperature of $1$ kilogram of water by $1 \cels$.

However, it is noted that this energy depends upon the initial temperature of the water itself.

Hence it is now usually defined as $1000$ times the value of the international calorie

This unit is generally used in the food industry to provide an estimate of the energy provided by particular foods.
