kW to kVA – Calculator, convert in 1 step, examples, table and formula

With this tool you can convert from kW to kVA or kVA to kW, easily, quickly and free any electric power, the calculation takes into account the power factor.

For greater ease we explain which formula is used for the conversion, how to perform the calculation in 1 single step, some examples , and a table with the main conversions from kW to kVA.

We also show the most common power factors of different constructions , appliances and motors.

How to convert kW to kVA in only 1 step.

How to convert kW to kVA in only 1 step

Step 1:

Divide the kW (KiloWatts) between the power factor (F.P). See the common power factors on this website: https://www.calculatorsconversion.com/en/the-power-factor-values-%E2%80%8B%E2%80%8Bfor-the-most-common/.

For example, if you have a microwave that consumes 1.2kW and has a power factor of 0.9, then you should divide 1.2kW by 0.9 to obtain 1.333kW. (1.2kW /0.9 = 1.333kVA)

Examples of conversions from kW to kVA, three-phase, two-phase and single-phase:

Example 1:

An elevator has a power of 22kW, with a power factor of 0.81, how many kVA does the elevator have?

Rta: // The solution is as simple as dividing 22kW / 0.81, as follows: 22 / 0.81 = 27.16.

Example 2:

An electric heater has 8kW, with a power factor of 0.99, how many kVA does the heater have?

Rta: // You must divide the 8kW between the power factor and the result will be: 8 / 0.99 = 8.08kVA, as you can see, the higher the power factor, the more similar are the kW and kVA, remember that the factor Power can not be greater than 1.

Example 3:

A ceiling fan has a power of 18kW, with a power factor of 0.89, how many kVA has a fan and fan?

Rta: // To know the kVA, the kW (18) must be divided between the power factor (0.89), the result will be: 18 / 0.89 = 20.22kVA.
