There seems to be an error in your definition. You state a 75
kilogram-force. There is no such thing as a kilogram force. Kilogram is a
unit of mass, newton is a unit of force. Please refrain from corrupting SI
units with the same nonsense that is a part of FFU. With FFU one doesn't
know what a pound is. Is it weight, is it mass, is it what? We claim SI to
be superior because it has avoided this trap by naming the kilogram as a
unit of mass and the newton as a unit of force/weight. Let's keep it that
way.
The definition states a 75 kilogram mass. A 75 kg mass has a weight of
735.499 N, or 735.5 N for all practical purposes. Thus the power required
to raise a 735.5 N ( a 75 kg mass) force at 1 m/s is 735.5 W.
metric horsepower
a unit of power, defined to be the power required to raise a mass of 75
kilograms at a velocity of 1 meter per second. This is approximately 735.499
watts or 0.986 32 horsepower. The unit is also known by its French name
cheval vapeur or its German name pferdestärke
