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:
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.
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.
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.
The first thing to enter the value of the kW you want to convert, then you must enter the power factor, if you do not know you can see in the tables above the most common values, finally you must click on calculate, if you need to do another calculation must click on restart.
