Note, For higher values like 5×10^{3}, 10×10^{6}, 1.6 x10^{12}, enter the value like this for scientific notation as 5e3, 10e6, 1.6e12, etc.
Conversion Using the Power Formula :
AC Single Phase Khw to Watts Calculation:
The Real Power (P) in Watts (W) is equal to 1000 times the Energy (E) in Kilowatthours (kWh), divided by the consumption time period t in hours (hrs):
For example, Let’s find the average watts of power for 3 kWh of energy used in 6.5 hours.
P_{(W)} = (3×1000) / 6.5
Watts = 461.53
Where:

 E= Energy in Kilowatthours (Kwh)
 P = Power in watts
 T = time in hours

Frequently asked questions
2 kilowatthour is defined as the amount of work done or energy consumed when a device of Real power kilowatt is used for 2 hours at rated voltage. It is the measurement of electrical energy equivalent to the Real power (P) consumption.
12 unit of electricity = 12 kWh. The electricity used is generally charged for in “unit of electricity'. Killowatthours is the product of watts x time (1 kilowatt = 1000 watts). A 4kilowatt heater switched on for 3 hours will have used 12 kilowatthours of electricity.
Kilowattshour (kWh) is the unit used to express the energy (E) consumption of an appliance or load.
Energy is defined as the product of power and time. For constant value, it is expressed as:
energy = power * time
Since a watt is a relatively small unit of electricity, it is common for it to be measured in multiples, like a kilowatt (kW). A kilowatt, as we mentioned, is just 1,000 watts (W).
