}Explanation
Formula: Metric horsepower = Horsepower × 1.01387. Why: horsepower and metric horsepower each have their own fixed watt equivalence, so the calculator normalizes through watts before applying the exact target definition.
Horsepower (hp): a mechanical power unit with a fixed watt equivalent, commonly used for engines, motors, and machinery ratings.
Metric horsepower (PS): a horsepower variant with its own fixed watt definition, often used in automotive and European technical specifications.
This route is useful when comparing motor and engine ratings across watts, kilowatts, horsepower, and metric horsepower without mixing the underlying definitions.
This conversion is purely multiplicative because both units reduce through watts using fixed power definitions with no offset.
