Convert Watt to Horsepower (Electrical)
Unit definitions
Watt
The watt is the SI unit of power. It is defined as one joule per second ($1\ \text{W} = 1\ \text{J/s}$).
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 Watt to Horsepower (Electrical)
$$\text{Power}_{\text{hpE}} = \frac{\text{Power}_{\text{W}}}{746}$$
Examples
Example 1
Convert $45.0\ \text{W}$ to $\text{hpE}$.
$$\text{Power}_{\text{hpE}} = \frac{45.0}{746}$$
$$\text{Power}_{\text{hpE}} = 0.060322$$
$$\therefore \ 45.0\ \text{W} = 0.060322 \ \text{hpE}$$
Example 2
Convert $70.0\ \text{W}$ to $\text{hpE}$.
$$\text{Power}_{\text{hpE}} = \frac{70.0}{746}$$
$$\text{Power}_{\text{hpE}} = 0.093834$$
$$\therefore \ 70.0\ \text{W} = 0.093834 \ \text{hpE}$$
Example 3
Convert $110.0\ \text{W}$ to $\text{hpE}$.
$$\text{Power}_{\text{hpE}} = \frac{110.0}{746}$$
$$\text{Power}_{\text{hpE}} = 0.147453$$
$$\therefore \ 110.0\ \text{W} = 0.147453 \ \text{hpE}$$
Example 4
Convert $150.0\ \text{W}$ to $\text{hpE}$.
$$\text{Power}_{\text{hpE}} = \frac{150.0}{746}$$
$$\text{Power}_{\text{hpE}} = 0.201072$$
$$\therefore \ 150.0\ \text{W} = 0.201072 \ \text{hpE}$$
Example 5
Convert $160.0\ \text{W}$ to $\text{hpE}$.
$$\text{Power}_{\text{hpE}} = \frac{160.0}{746}$$
$$\text{Power}_{\text{hpE}} = 0.214477$$
$$\therefore \ 160.0\ \text{W} = 0.214477 \ \text{hpE}$$
