What does one gigawatt represent?

One gigawatt equals one billion watts and is commonly used to measure large electrical power capacities such as power plants.

Why are there different types of horsepower?

Horsepower has several variants including mechanical, metric, and electrical, each defined by slightly different power values, which impacts conversions.

When is converting gigawatts to horsepower useful?

This conversion is useful to compare large electrical power values to mechanical power ratings for engines, industrial machinery, or vehicle specifications.
