What does one gigawatt-hour represent in energy?

One gigawatt-hour is the energy delivered by one gigawatt of power over one hour, equal to 3.6 × 10¹² joules.

Why convert gigawatt-hours to kilojoules?

Converting to kilojoules allows expressing large-scale electrical energy in a smaller unit commonly used in scientific and engineering work.

Where is the kilojoule unit typically used?

Kilojoules quantify work, heat, and energy transfer in scientific, nutritional, and engineering contexts.

Can I use this conversion for nutrition energy calculations?

While kilojoules are used in nutrition, gigawatt-hours represent very large scales not typical for dietary energy measurements.
