Prove that 1HP = 746 Watts

Horsepower and Watts are the two different units of power. Power can be either electric or mechanical and can be converted between the two.

We know that 1 pound = 4.448 N

550-foot pounds per seconds is converted into metric units:

550 x 0.3048 x 4.448 Nm.s-1

1 foot = 0.3048m

1HP = 550 foot-pound per second

1 pound = 4.448N

1 foot = 0.3048m

1HP = 550 x 4.448 x 0.3048 m

1HP = 745.69 Nm.s-1
