When you need to convert kilowatts to horsepower

  • Comparing engine or motor output quoted in horsepower, metric horsepower or kilowatts.
  • Sizing heating and cooling equipment rated in BTU per hour or watts.

Common mistakes to avoid

  • Dividing when you should multiply. Because 1 kilowatt = 1.34102 horsepower, the answer should be larger than the number you started with.
  • Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.

How precise does the answer need to be?

Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.

How these units are defined

  • Kilowatt (kW): 1,000 watts; engine and appliance power in metric markets. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
  • Horsepower (hp): Mechanical horsepower: exactly 550 foot-pounds per second. The accepted value is a measured or conventional figure rather than an exact definition, so the factor shown is rounded.
