All About Kilowatts (kW) And Kilowatt Hours (kWh)
This will give you the number of watt-hours consumed each day. 1200 W × 3hr = 3600 Wh. But in reality, we need to convert Watt hours (Wh) to Kilowatt hours (kWh). One kilowatt equals 1000 watts, so to calculate how many kWh a device uses, divide the watt-hours by 1000, and you get your watts/hr. 3600 Wh / 1000 = 3.6 kWh.

Kilowatt-Hours: A Guide To Understanding Electrical Power
A kilowatt-hour (kWh) means that 1,000 watts are used in an hour. Therefore, a kilowatt-hour (1,000 watts/hr) is more commonly used to account for household electricity consumption. Returning to our example of the 100-W light bulb, the bulb has to be turned on for 10 hours to consume one kWh of electricity.
Kilowatt Hours kWh Explained
There are 60 minutes in an hour and 60 seconds per minute, so 60 multiplied by 60 gives us 3,600 seconds per hour. We can then convert the 30 seconds runtime into hours by dividing the 30 seconds by 3,600. That means we will run for 0.0083 hours. Two kilowatts multiplied by 0.0083 hours equals 0.0167 kilowatt hours.

kW vs. kWh: Watts, Kilowatts, and Kilowatt-Hours Explained
If you leave a 100-watt bulb on for an hour, you''ve used 100 watt-hours. Again, a kilowatt of power (kW) is 1,000 watts, so if you leave ten 100-watt bulbs (1 kW of bulbs) on for an hour, you''ll have used one kilowatt-hour (kWh). This is one reason why switching to more energy efficient light bulbs can have such a great impact.
