Horsepower is the unit of the measurement of the power; it is the rate of the work which is done. The unit mechanical horsepower is also known as the imperial horsepower, and its value is defined as 745.7 watts, and the value of the metric horsepower is equal to the 735.5 watts.

## hp to kW

The value of the horsepower unit is adopted by the Scottish engineer James watt; he is also the founder of the unit watt. In the one horsepower, the electronic equivalent is 74+6 watts in the international system of the units. The unit horsepower is the output shaft of the engine, turbines and any other machines like this. The horsepower is larger for the reciprocating engines.

**Kilowatt:**

A kilowatt is a unit of energy. There are two terms which are kilowatt power and the kilowatt energy still we are confused between both of these terms. The term power is the rate of the delivery of the energy, and it is also the work performance per unit of the time. The kilowatt-hour is mainly used as the billing unit of the energy which is delivered to the consumers by the electric utilities; this is the term energy or the kilowatt hours.

The higher the value of the power level and the quicker the battery storage where energy is delivered. The unit kilowatt is derived from the international system of the unit which is joule. If the power of this kilowatt-hour unit is high, then the battery stored energy will be the depleted in the shorter period.
