Power is the rate of energy use or transfer. Watts and kilowatts are the SI units used for electricity and appliances, while horsepower is still standard for engines — though mechanical horsepower (745.7 W) and metric horsepower (735.5 W) differ slightly. This category also covers BTU per hour for heating and cooling equipment ratings.
