An electric furnace is using approximately how many kilowatts if it is rated at 15,500 watts?

To determine the kilowatt rating of an electric furnace rated at 15,500 watts, it's essential to understand the relationship between watts and kilowatts. The conversion from watts to kilowatts is straightforward: you divide the number of watts by 1,000.

In this case, 15,500 watts divided by 1,000 equals 15.5 kilowatts. This conversion is crucial, especially when dealing with larger electrical appliances, as it helps in understanding their power consumption in more manageable terms.

Choosing the correct answer involves accurately converting the wattage to kilowatts, which confirms that the furnace is indeed operating at 15.5 kW. This conversion is a fundamental concept in electrical applications and is part of understanding how to calculate energy use efficiently in HVAC systems.
