Convert Horsepower (Imperial) to Horsepower (Electrical)
Unit definitions
Horsepower (Imperial)
The imperial horsepower is defined as $550$ foot-pounds per second (i.e., the ability to raise $550$ pounds by a foot within a second). One imperial horsepower is approximately $745.7$ watts.
Horsepower (Electrical)
The electrical horsepower is defined as exactly $746$ watts. It is used to measure the power output of electric motors and generators.
How to convert Horsepower (Imperial) to Horsepower (Electrical)
$$\text{Power}_{\text{hpE}} = \text{Power}_{\text{hp}} \cdot 0.9995976830861528150134048257372654$$
Examples
Example 1
Convert $20.0\ \text{hp}$ to $\text{hpE}$.
$$\text{Power}_{\text{hpE}} = 20.0 \cdot 0.9995976830861528150134048257372654$$
$$\text{Power}_{\text{hpE}} = 19.991954$$
$$\therefore \ 20.0\ \text{hp} = 19.991954 \ \text{hpE}$$
Example 2
Convert $90.0\ \text{hp}$ to $\text{hpE}$.
$$\text{Power}_{\text{hpE}} = 90.0 \cdot 0.9995976830861528150134048257372654$$
$$\text{Power}_{\text{hpE}} = 89.963791$$
$$\therefore \ 90.0\ \text{hp} = 89.963791 \ \text{hpE}$$
Example 3
Convert $120.0\ \text{hp}$ to $\text{hpE}$.
$$\text{Power}_{\text{hpE}} = 120.0 \cdot 0.9995976830861528150134048257372654$$
$$\text{Power}_{\text{hpE}} = 119.951722$$
$$\therefore \ 120.0\ \text{hp} = 119.951722 \ \text{hpE}$$
Example 4
Convert $135.0\ \text{hp}$ to $\text{hpE}$.
$$\text{Power}_{\text{hpE}} = 135.0 \cdot 0.9995976830861528150134048257372654$$
$$\text{Power}_{\text{hpE}} = 134.945687$$
$$\therefore \ 135.0\ \text{hp} = 134.945687 \ \text{hpE}$$
Example 5
Convert $185.0\ \text{hp}$ to $\text{hpE}$.
$$\text{Power}_{\text{hpE}} = 185.0 \cdot 0.9995976830861528150134048257372654$$
$$\text{Power}_{\text{hpE}} = 184.925571$$
$$\therefore \ 185.0\ \text{hp} = 184.925571 \ \text{hpE}$$
