SwitchExplanation
Formula: Kilowatts = Horsepower × 0.7457. 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.
Kilowatts (kW): a power unit equal to 1,000 watts, common for appliances, EV chargers, motors, and electrical system ratings.
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.
