kW-kVA to Power factor – calculation, formula, table, convert free.

With this calculator you can convert from kW/kVA to power factor with the explanation of the conversion formula.

In addition to the calculator , we explain some examples , some equivalences in a table and finally the steps for the conversion from kW-kVA to PF (power factor).

kW-kVA to Power factor calculation formula:

formula kw kva to fp power factor

  • kW=One kilowatt is equal to 1000 watts.
  • kVA=kiloVolt-Ampere.
  • P.F=Power factor

How to convert kW-kVA to Power factor in only 1 step.

kW-kVA to Power factor

Step 1.

Divide kW between kVA, for example, if you have a microwave that consumes 1kW and 1,2kVA, you must divide 1kW between 1,2kVA, the result will be a power factor of 0.83. (1kW /1,2kVA = 0,83)

Definition P.F, S (kVA) and P (kkW):

kW: kW stands for kilowatt. A kilowatt is simply 1,000 watts, which is a measure of power. So, for example, the 10,000 watt electric shower in the top bullet point above could also be called a 10 kilowatt shower.

kVA: A kilovolt-ampere, commonly referred to as a kVA, is commonly used as a unit of power in obtaining the electrical capacity of circuit breakers, uninterrupted power supplies and wirings.

KVA is larger than KW because loads are inductive such as motors, discharge lighting, reactors and more current is required to keep the magnetic field energized than is -turned into heat (KW).

Inductive devices or loads such,. as tansformers and motors having power factor less than 1.0 are generally rated in KVA.

P.F: Power factor is the ratio of working power to apparent power. It measures how effectively electrical power is being used. A high power factor signals efficient utilization of electrical power, while a low power factor indicates poor utilization of electrical power.

Power Factor is the cosine of the phase angle between current and voltage.
Power Factor is the ratio of true power to apparent power.
