Convert Horsepower (Imperial) to Watt
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.
Watt
The watt is the SI unit of power. It is defined as one joule per second ($1\ \text{W} = 1\ \text{J/s}$).
How to convert Horsepower (Imperial) to Watt
$$\text{Power}_{\text{W}} = \text{Power}_{\text{hp}} \cdot 745.69987158227$$
Examples
Example 1
Convert $25.0\ \text{hp}$ to $\text{W}$.
$$\text{Power}_{\text{W}} = 25.0 \cdot 745.69987158227$$
$$\text{Power}_{\text{W}} = 18642.49679$$
$$\therefore \ 25.0\ \text{hp} = 18642.49679 \ \text{W}$$
Example 2
Convert $75.0\ \text{hp}$ to $\text{W}$.
$$\text{Power}_{\text{W}} = 75.0 \cdot 745.69987158227$$
$$\text{Power}_{\text{W}} = 55927.490369$$
$$\therefore \ 75.0\ \text{hp} = 55927.490369 \ \text{W}$$
Example 3
Convert $110.0\ \text{hp}$ to $\text{W}$.
$$\text{Power}_{\text{W}} = 110.0 \cdot 745.69987158227$$
$$\text{Power}_{\text{W}} = 82026.985874$$
$$\therefore \ 110.0\ \text{hp} = 82026.985874 \ \text{W}$$
Example 4
Convert $130.0\ \text{hp}$ to $\text{W}$.
$$\text{Power}_{\text{W}} = 130.0 \cdot 745.69987158227$$
$$\text{Power}_{\text{W}} = 96940.983306$$
$$\therefore \ 130.0\ \text{hp} = 96940.983306 \ \text{W}$$
Example 5
Convert $185.0\ \text{hp}$ to $\text{W}$.
$$\text{Power}_{\text{W}} = 185.0 \cdot 745.69987158227$$
$$\text{Power}_{\text{W}} = 137954.476243$$
$$\therefore \ 185.0\ \text{hp} = 137954.476243 \ \text{W}$$
