What is a gigawatt?
A gigawatt is one billion watts — the scale of national grids and large nuclear plants.
Definition: Exactly 1×10⁹ watts.
Where it is used: National electricity demand, total installed renewable capacity, and large nuclear reactor output.
What is a metric horsepower?
Metric horsepower, written PS or CV, is the continental European engine power unit.
Definition: Defined as 75 kilogram-force meters per second, which is exactly 735.49875 watts.
Where it is used: German, French, Italian and Japanese vehicle specifications, where power is quoted in PS, CV or ps.
Worth knowing: About 98.6% of a mechanical horsepower, which is why converted figures never come out as round numbers.
