Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 1.6e12, etc.
Conversion Using the Power Formula :
AC Single Phase Watts to KVA Calculation:
The apparent power (S) in kilovolt-amps (kVA) is equal to the Real Power (P) in watts (W), divided by 1000 times the power factor Pf:
For example, Let’s convert 8000 watts to kVA given a power factor of 0.90.
S(KVA) = 8000 ÷ 1000 x 0.90
KVA = 7.200
Where:
-
- S = Apparent Power in Kilo-volt-amps (Kva)
- P = Real Power in Watts (W)
- Cosθ = Power factor in AC circuits

Frequently asked questions
kVA Is short for kilovolt-amperes. It’s a unit of measurement used to refer to electricity in the form of “apparent power” in an AC (alternating current ) or DC (direct current) electrical circuit.
It’s measured as the product of the voltage, which represents electrical pressure, and the electrical current (amperes).
KVA stands for kilovolt-amperes. kilo is the scientific prefix for 1000 & in a purely resistive system a volt-ampere is a watt, therefore in a purely resistive system 1000 watts = 1000 volt-amperes = 1 KVA.
Solution: The formula for the conversion of KVA to KW is as follows: KVA × pf = KW, where pf is the power factor.
What is a unit of electricity? 1 unit of electricity is equal to one kilowatt-hour. It is the amount of power required to use an appliance of 1000 watts or, 1kW power rating for an hour.
If you have a 1A circuit, 1 volt is equal to 1W. However, amps make the difference, too. So at 10A, 1 volt is equal to 10W. And if you have a 100A circuit, 1 volt is equal to 100W.
