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 KW to Kwh Calculation:
The Energy (E) in kilowatthours (kWh) is equal to the Real power (P) in kilowatts (kW), times the time period t in hours (h):
For example, let’s convert 30 kW power used over a 6 hour time period to energy in kWh.
E_{(Kwh)} = 30 ÷ 6
E_{(Kwh)} = 180
Where:

 P = Power in KW
 T = time in hours (hrs)
 E = Energy In Kilowatthours (Kwh)

Frequently asked questions
A KVA is simply 1000 voltamps. A volt is an electrical pressure. An amp is an electrical current. A term called apparent power (the absolute value of complex power, S) is equal to the product of the volts and amps.
5 units of electric energy are equal to 5 kilowatt hours (kWh) and in simple words, 5 kWh is the quantity of energy consumed by a 5kW (5000 watts) electric appliance in 1 hour.
That's it! In other words, watt=amp X volt. Sometimes you will see this formula written as W=A X V. For example, if the current is 5 amps (5A) and the voltage is 220V, you multiply 5 by 220, to get 1100W (watts).
Therefore, a 2ton AC removes 24,000 BTUs of heat from the room per hour, or 7 kilowatts (kW).
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running.
