What is a Kwh (Kilowatt Hour)?

In short, a Kwh (Kilowatt Hour) is the amount of energy in Kilowatts that something uses in 1 hour.

Most appliances show a power usage of watts, so if your washine machine showed 1600W on the plug then it would use 1600W per hour, giving it a power usage of 1.6Kwh.

How do I find out my Kwh price?

The best place is on your electricity bill, but here are some common Kwh prices from around the world...

UK = £0.14

USA = $0.16

CANADA = $0.11

How can we quickly calculate the price to run the item?

To work out how much is costs you to run the item for a certain period of time do the following...

(Watts x Hours x Price Per Kwh You're Charged) / 1000 = Price Per Hours in Whole Currency

So using this example...

(600w x 24 Hours x £0.14 Kwh) / 1000 = £1.84 Per Day
