How to Convert kVA to Horsepower
Kilovolt-amps, or kVA, are a measure of the apparent power in a circuit, and horsepower is a measure of electrical output power.
kVA to Horsepower formula
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.
P(HP) = S(kVA) × η × PF / 0.746
Thus, the power P in horsepower is equal to the apparent power S in kVA times the motor efficiency η times the power factor PF, divided by 0.746 kW/HP.
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 converting kilovolt-amps to kilowatts. Multiply kVA by the power factor, then multiply that by the efficiency if available.
P(kW) = S(kVA) × η × PF
Step Two: Convert to Horsepower
Finally, divide the kilowatts by 0.746 to get the final result in horsepower.
P(HP) = P(kW) / 0.746
For example, let’s convert 10 kVA to horsepower using a power factor of 0.8 and a motor efficiency of 84%
HP = 10 kVA × 0.84 × 0.8 / 0.746
HP = 6.72 kW / 0.746
HP = 9.008 HP
