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 KVA to Watts Calculation:
The Real power (P) in watts (W) is equal to 1000 times the Apparent power (S) in kilovolt-amps (kVA), times the power factor (pf):
For example, let’s convert 12 kVA to watts using a power factor of 0.8.
0.8P(W) = 1000 x 12 x
P(w) = 9600 W
Where:
-
- P = Power in watts
- S = Apparent Power in Volt-amps (VA)
- Cosθ = Power factor in AC circuits

Frequently asked questions
For a 10 KVA generator at unity power factor (1.0), the maximum output is 10000 watts (volts x amps x power factor / 1000), but at 0.8 power factor (Some Crommelins generators) it will be 8000 watts.
To calculate the kVA rating for a single-phase transformer, you will need to multiply the required input voltage (V) by the required current load in amperes (l) and then divide that number by 1,000: V * l / 1,000.
The conversion of watts to kilowatts is just as straightforward as you may have guessed. We find the Real power in kilowatts Power (kW) by dividing the Real power in watts Power (W) by 1,000.
A kilowatt is a unit of power representing a rate of 1000 watts of electrical energy.
3 unit of electricity = 3 kWh. The electricity used is generally charged for in “unit of electricity'. Kilowatt-hours is the product of watts x time (1 kilowatt = 1000 watts).
