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.
