What is a gigawatt (GW)?

A gigawatt is an SI unit of power equal to one billion watts, commonly used for measuring large-scale electrical power output such as that from power plants.

What does kilocalorie (IT)/hour represent?

Kilocalorie (IT)/hour is a unit of power describing the rate of energy transfer based on delivering international table kilocalories each hour, often used in heating or metabolic rate contexts.

Why convert from gigawatt to kilocalorie (IT)/hour?

Converting between these units helps compare or relate large electrical power values to thermal energy rates used in heating, cooking, and biological energy consumption.
