Horsepower and Watts Conversion

Conversion calculator which helps to convert hp to watts and watts to hp using available units such as mechanical, metric and electrical.

[tabs][tab title=”Formula:”]

Horsepower (HP) =W/HP

Where,

• W = Power in wattsHP = Value of one HP
• 1 Electrical HP = 746 watts
• 1 Mechanical HP = 745.69987 watts
• 1 Metric HP = 735.49875 watts

Mechanical :

One mechanical horsepower is equal to 745.699872 watts

1 hp(I) = 745.699872 W

So the power conversion of horsepower to watts is given by

P(W) = 745.699872 * P(hp)

Examples :

Convert 5 hp to watts

P(W) = 745.699872 * 5 hp = 3728.495 W

Convert 5W to mechanic horsepower

P(hp) = 5W / 745.699872 = 0.00671 hp

Electrical :

One electrical horsepower is equal to 746 watts

1 hp(E) = 746 W

So the power conversion of horsepower to watts is given by

P(W) = 746 * P(hp)

Examples :

Convert 5 hp to watts:

P(W) = 746 * 5 hp = 3730 W

Convert 5W to electrical horsepower

P(hp) = 5W / 746 = 0.0067 hp

Metric :

One metric horsepower is equal to 735.49875 watts

1 hp(M) = 735.49875 W

So the power conversion of horsepower to watts is given by

P(W) = 735.49875 * P(hp)

Examples :

Convert 5 hp to watts

P(W) = 735.49875 * 5 hp = 3677.49 W

Convert 5W to metric horsepower

P(hp) = 5W / 735.49875 = 0.0679 hp
