To convert watts to kilowatt hours, it's important to understand the relationship between these units.

Watts measure power (the rate at which energy is used or generated), while kilowatt hours measure energy (the total amount of power consumed over time). One kilowatt (kW) is equal to 1,000 watts. Therefore, to convert watts to kilowatts, you divide by 1,000.

In this case, 746 watts can be converted to kilowatts as follows:

746 watts ÷ 1,000 = 0.746 kilowatts.

Now, when considering the time over which this power is used, if we assume a period of 1 hour, the energy consumption would be:

0.746 kilowatts × 1 hour = 0.746 kilowatt hours.

Since the question is asking for the energy equivalent of 746 watts in terms of kilowatt hours, and if you base the calculation on a one-hour usage, 746 watts indeed equates to 0.746 kilowatt hours.

This understanding of the conversion process solidifies that the correct response is accurate in reflecting the relationship between power and energy consumption over a specific time frame.
