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 KW to Kwh Calculation:
The Energy (E) in kilowatt-hours (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 Kilowatt-hours (Kwh)

Frequently asked questions
A KVA is simply 1000 volt-amps. 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 2-ton 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.
