Metric horsepower is exactly defined as 0.73549875 kW (kilowatts), that is roughly 98.6% of US mechanical horsepower.Metric horse power is widely used in auto industry to indicate power of car engines in Europe and Asia. French, Japanese, Korean, German, Swedish, Italian and other automobile companies use this unit.
more pronounced with drives of smaller horsepower ratings. As shown in the following example, this reduction in efficiency is not as detrimental as it first seems. Example Consider a VFD coupled to a motor that requires 16.4 kilowatts (kW) to deliver 20 shaft hp to an exhaust fan when operated at its full rated speed. At half its rated operating
The power required to drive the pump at the rated design condition should always be less than the nameplate horsepower rating of the motor. So if the pump will require 4.5 HP at the design condition, at a minimum, the motor should be sized for 5 HP – the next nominal size above 4.5 HP.

Motors of higher speed usually take a lower current than that shown in the table; while motors of lower speed usually take higher current. Wide variations from these figures can arise, especially on single phase motors, and engineers should, whenever possible, determine the actual f.l.c from the motor rating plate in each case.
Kilowatt. Definition: A kilowatt (symbol: kw) is a unit of power in the International System of Units (SI). The base unit of the kilowatt is the watt, which was named after Scottish inventor James Watt. As is consistent with SI units, the prefix kilo- means that a kilowatt equals one thousand watts or one thousand joules per second.
