Enter any two of kVA, power factor, or horsepower to calculate the missing value. This conversion uses HP = (kVA × PF) / 0.746 and kW = kVA × PF.
kVA to Hp Formula
HP = \dfrac{\text{kVA}\times \text{PF}}{0.746}To convert kVA to horsepower, multiply kVA by the power factor to get kW, then divide by 0.746 to convert kW to hp. Equivalently, HP = (kVA × PF)/0.746 and kW = kVA × PF.

Example Problem
Use the following example problem to compare with the output from the calculator above and confirm the results.
- Given apparent power of 25 kVA and power factor of 0.80.
- Use the formula HP = (kVA × PF)/0.746.
- Plug in the values: HP = (25 × 0.80)/0.746 = 20/0.746.
- The result is approximately 26.810 hp.
