Kilowatts to Horsepower

1 kilowatt = 1.341 horsepower · 1 hp = 0.7457 kW

1 kilowatt = 1.341 horsepower

How it’s calculated

hp = kW × 1.34102209

  • Multiply the value in kilowatts by 1.34102209.
  • To go back, divide by 1.34102209 (or multiply by 0.7456998716).
  • 1 kW = 1.34102209 hp · 1 hp = 0.7456998716 kW
Show worked solutionFactor, unit cancellation and rounding, step by step

  1. Find the conversion factor

    By definition 1 kW = 1000 W and 1 hp = 745.69987158227 W, so 1 kW = 1.34102208959503 hp. Source: BIPM SI Brochure (9th ed.) (SI prefixes and accepted units); NIST SP 811 / Handbook 44.

  2. Multiply by the factor written as a fraction

    Put kW in the denominator so it cancels, leaving hp.

  3. Calculate (unrounded)

  4. Round the answer

    Rounded to 5 significant figures.
