What is the formula used to calculate horsepower from foot pounds of work done?

The correct formula to calculate horsepower from foot-pounds of work done is Horsepower = (Foot Pounds x Time) / 550. This formula derives from the definition of horsepower, which measures the rate at which work is done.

In the context of mechanical work, one horsepower is defined as 550 foot-pounds of work completed in one second. Therefore, to find horsepower, you multiply the foot-pounds of work by the time in seconds during which that work was done, and then divide by 550 to convert the result into horsepower. This conversion factor allows for a standard understanding of power output relative to work performed over time.

Using this formula ensures that calculations align with the established relationship between work and power in mechanical systems, emphasizing the significance of both the amount of work done and the time taken to perform that work.
