Hp to kVA Formula

The following formula is used to calculate the kVA from horsepower and power factor.

kVA = (Hp * 0.746) / PF

Variables:

  • kVA is the apparent power in kilovolt-amperes
  • Hp is the horsepower
  • PF is the power factor

To calculate the kVA, multiply the horsepower by 0.746 and then divide by the power factor.

What is Horsepower to kVA Conversion?

Horsepower to kVA conversion is the process of converting the power output of an engine or motor (measured in horsepower) to the apparent power (measured in kilovolt-amperes). This conversion is essential in electrical engineering and power systems to ensure that the electrical supply can handle the power requirements of the machinery. The power factor, which is a measure of how effectively the electrical power is being used, plays a crucial role in this conversion.

How to Calculate Hp to kVA?

The following steps outline how to calculate the Hp to kVA.


  1. First, determine the horsepower (Hp) of the motor or engine.
  2. Next, determine the power factor (PF) of the system.
  3. Next, calculate the kVA using the formula kVA = (Hp * 0.746) / PF.
  4. Finally, verify the calculated kVA with the given values.
  5. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Horsepower (Hp) = 10

Power Factor (PF) = 0.8

kVA = (10 * 0.746) / 0.8 = 9.325 kVA
