Understand Conversion Factors: Understand the conversion factors needed to convert horsepower to (ft⋅lb)/s. One horsepower is defined as 550 foot-pounds per second (ft⋅lb/s).
Multiply Given Horsepower: Multiply the given horsepower by the conversion factor to get the equivalent in (ft⋅lb)/s. Since 1 hp =550(ft⋅lb)/s, to convert 4 hp to (ft⋅lb)/s, we multiply 4 by 550. Calculation: 4 hp ∗550(ft⋅lb)/s per hp 11(ft⋅lb)/s
