How to convert watts to horsepower

How to convert power in watts (W) to horsepower (hp).

Watts to mechanic / hydraulic horsepower

1 mechanic or hydraulic horsepower is equal to [745.699872] watts.

1 hp(I) = 745.699872 W

So  power conversion of watts to horsepower is given by.

P(hp) = P(W) / 745.699872

Example 1

Convert 15W to mechanic horsepower:

P(hp) = 15W / 745.699872 = 0.02011 hp

Example 2

Convert 20W to mechanic horsepower:

P(hp) = 20W / 745.699872 = 0.02682 hp

Example 3

Convert 50W to mechanic horsepower:

P(hp) = 50W / 745.699872 = 0.06705 hp

Watts to electrical horsepower

1 electrical horsepower is equal to [746] watts.

1 hp(E) = 746 W

So power conversion of watts to horsepower is given by.

P(hp) = P(W) / 746

Example 1

Convert 15W to electrical horsepower:

P(hp) = 15W / 746 = 0.02010 hp

Example 2

Convert 20W to electrical horsepower:

P(hp) = 20W / 746 = 0.02680 hp

Example 3

Convert 50W to electrical horsepower:

P(hp) = 50W / 746 = 0.06702 hp

Watts to metric horsepower

1 metric horsepower is equal to [735.49875] watts.

1 hp(M) = 735.49875 W

So  power conversion of watts to horsepower is given by.

P(hp) = P(W) / 735.49875

Example 1

Convert 15W to metric horsepower:

P(hp) = 15W / 735.49875 = 0.02039 hp

Example 2

Convert 20W to metric horsepower:

P(hp) = 20W / 735.49875 = 0.02719 hp

Example 3

Convert 50W to metric horsepower:

P(hp) = 50W / 735.49875 = 0.06798 hp
