Frequently used with a number (e.g., 200 horsepower). The word does not change form in the plural: you say 300 horsepower, not 300 horsepowers. Commonly shortened to 'hp' in writing. Appears in discussions about cars, trucks, motorcycles, boat motors, and other machinery where engine strength matters.
