What is the calorie (IT) unit used for?

The calorie (IT) is a historical energy unit primarily used in classical thermodynamics and steam-engine calculations, defined by the heat needed to raise 1 gram of water by 1 °C.

How does a watt-second relate to other energy units?

A watt-second is an energy unit equal to one watt of power applied over one second and is dimensionally identical to the joule.

Why convert calorie (IT) to watt-seconds?
