To determine how many kilowatt hours are equivalent to 746 watts, it's important to understand the relationship between watts and kilowatts. One kilowatt is equal to 1,000 watts. Therefore, to convert 746 watts into kilowatts, you divide by 1,000:

746 watts ÷ 1,000 = 0.746 kilowatts.

Now, a kilowatt hour (kWh) is a measure of energy equivalency that indicates how much energy is consumed over time. When considering power over one hour, the 746 watts can be expressed as 0.746 kilowatts for that same one-hour period. Hence, if a device uses 746 watts for one hour, it will consume 0.746 kilowatt hours of energy.

This makes the answer of 0.746 kilowatt hours correct, reflecting the direct conversion from watts to kilowatts, and then the time component to arrive at kilowatt hours.
