How many manpower are there in a horsepower?

Answer 1

In the context of power measurement, one horsepower is equivalent to 550 foot-pounds per second or approximately 745.7 watts. Manpower, on the other hand, refers to the power generated by a human being, which can vary depending on the individual and the task being performed. Therefore, it is not accurate to convert horsepower directly to manpower as they represent different units of power.

Answer 2

While horsepower is quantifiable in specific SI units (it's about 745.7 watts), manpower is a general term that measures the "power" in terms of numbers of men only. One man might be stronger than another and capable of doing more work (applying more force), but that isn't a concern for applying the more general term manpower. When clearing the refuse from a vacant lot, it will go faster if there is more manpower. More people, more work per unit time. Nothing but an abstraction. If someone brings up the term manpower, don't scramble to get out your calculator and start to panic because the conversion factor doesn't immediately come to mind. There isn't one.
