How many foot-pounds per minute is 1 mechanical horsepower equal to?

One mechanical horsepower is defined as the ability to do work at the rate of 33,000 foot-pounds per minute. This value originates from historical calculations related to the work done by steam engines and was standardized to provide a consistent measure of power output.

To understand this conversion, consider that power represents work done over time. In mechanical terms, one horsepower equates to performing 33,000 foot-pounds of work in one minute, indicating that a machine or engine with a power capacity of one mechanical horsepower can lift 33,000 pounds one foot in a minute or do an equivalent amount of work in varied applications.

Therefore, 33,000 foot-pounds per minute is the correct measure of one mechanical horsepower. The other values provided do not align with this historical definition and standard, making them incorrect in the context of mechanical horsepower comparisons.
