The correct answer is 746 watts.

Key Points

  • Horsepower is the unit of measurement of power.
  • It was first used by James Watt.
  • 1 hp is approximately equal to 746 watts or 0.746 kW.
  • To convert from horsepower to watts, multiply by 746.

Additional Information

  • In 1784, James Watt introduced the first steam engine to the public.
  • To measure the power of the unit he invented and created, Watt coined the term "horsepower", which he had previously developed. 
  • In 1960, the official SI unit of power was established in watts.
