How to Convert kVA to Horsepower
Kilovolt-amps, or kVA, are a measure of the apparent power in a circuit and horsepower is also a measure of power. Because motor efficiency and power factor reduce the amount of apparent power that can be transformed into actual work, the formula below is needed to convert.
kVA to Horsepower formula
HP = (kVA × Efficiency × Power Factor) ÷ 0.746
Horsepower is equal to kVA the motor efficiency times the power factor, divided by 0.746.
For the conversion, replace kVA, efficiency, and power factor values in the formula above, then solve, or just use the calculator above, which does the same thing.
To use the formula, follow these two steps.
Step One: Convert to kW
To convert kVA to horsepower, start by finding the result in kilowatts. Multiply kVA by the power factor, then multiply that by the efficiency if available.
Step Two: Final Conversion
Finally, divide the kilowatts by 0.746 to get the final result in horsepower.
For example, let’s convert 10 kVA to horsepower using a power factor of 80% and a motor efficiency of 84%
HP = (10 kVA × 0.84 × 0.8) ÷ 0.746
HP = 6.72 ÷ 0.746
HP = 9.008 HP
