What is a gigajoule used to measure?

A gigajoule is used to quantify large amounts of thermal, mechanical, or chemical energy, often in heating consumption, fuel content, or industrial energy processes.

How is a gigawatt-hour defined?

A gigawatt-hour represents the energy of one gigawatt of power sustained for one hour, commonly used for electrical energy production, consumption, and storage measurements.

Why is this conversion important in the energy sector?

Because it allows comparison and aggregation of different energy forms like thermal and electrical energy, aiding in energy management, planning, and policy decisions.
