How much electricity am I being charged?

They are two different amounts.

230w for 1 hour is 0.230kwh

2.7kwh in an hour is 2700w

Your PC isn’t drawing 2700w for an hour but it may draw 2.7kwh over the course of many hours or a day.

So according to my plug, I've used 2.7 kWH over 11 hours = £7.28

But 230w for 11 hours = £0.62

2.7 kWh over 11 hours does not equal £7.28.

2.7 kWh already factors in the time.

"Kilowatt (kW)
A unit of power that measures the rate at which a device uses or generates energy. One kilowatt is equal to 1,000 watts.
Kilowatt-hour (kWh)
A unit of energy that measures the total amount of electricity used or the capacity to use it. One kilowatt-hour is the amount of energy used when electricity is used at a rate of 1,000 watts for one hour."

So if your PC uses 2.7kWh over 11 hours, it means it is using roughly 0.25kWh per hour.

Which is very similar to your "rate" of 230W, or 0.23kW
 
If your unit rate is 25p and your PC has used 2.7 units in 11 hours then it's cost you 67.5p or 6.1p an hour and it's averaged 245w over those 11 hours.

Thanks, that makes sense. BTW, does anyone have Tapo plugs they extract the data from and put it into something like Grafana?
