1. The problem statement, all variables and given/known data

If the average KWH used per month in a household is 1650KWH for the year, what is the average power consumption rate in watts that gives this average KWH energy value?

2. Relevant equations

KWH X 1000WH/1KWH = W?

3. The attempt at a solution

1650KWH x 1000WH/1kWH = 1.65x106 W

Is this right?

No, KiloWatt-Hour is a unit of energy, Watts are a rate of energy.

1 kilowatt-hour is the number of Joules generated in 1 hour at a rate of 1 kilowatt. With this, you should be able to calculate what rate the question is looking for.
