What does one Calorie (nutritional) represent?

One Calorie (capital C) indicates a kilocalorie, which equals 1,000 small calories and corresponds to 4184 joules of energy, measuring food energy content.

What is a watt-second [W*s]?

A watt-second is an energy unit equal to the energy delivered by a power of one watt over one second, identical in dimension to a joule.

Why convert calories to watt-seconds?

Converting calories to watt-seconds links dietary energy to physical energy units, facilitating scientific calculations in fields like nutrition, physics, and engineering.
