How many kilowatt hours is equal to one horse power?

To understand the conversion between horsepower and kilowatt hours, it is important to know the definitions and equivalences involved. One mechanical horsepower is equivalent to approximately 0.746 kilowatts.

When dealing with energy usage over time, we relate kilowatts to kilowatt hours (KWH). If you operate a device that uses one horsepower continuously for one hour, it consumes about 0.746 KWH. This means that the closest approximation for the energy consumption for one horsepower used for one hour is about 0.746 KWH.

The given answer of 0.75 KWH can be considered a practical rounding of this value. Therefore, it is correct in a practical sense for when horsepower is referred to in terms of energy consumption over the time duration of one hour. Awareness of such conversions is crucial for HVAC professionals, especially when calculating energy usage and efficiency of heating and cooling systems.
