Convert Watt to Milliwatt
Unit definitions
Watt
The watt is the SI unit of power. It is defined as one joule per second ($1\ \text{W} = 1\ \text{J/s}$).
Milliwatt
$10^{-3}$ watts is a milliwatt.
How to convert Watt to Milliwatt
$$\text{Power}_{\text{mW}} = \text{Power}_{\text{W}} \cdot {10}^{3}$$
Examples
Example 1
Convert $35.0\ \text{W}$ to $\text{mW}$.
$$\text{Power}_{\text{mW}} = 35.0 \cdot {10}^{3}$$
$$\text{Power}_{\text{mW}} = 35000$$
$$\therefore \ 35.0\ \text{W} = 35000 \ \text{mW}$$
Example 2
Convert $75.0\ \text{W}$ to $\text{mW}$.
$$\text{Power}_{\text{mW}} = 75.0 \cdot {10}^{3}$$
$$\text{Power}_{\text{mW}} = 75000$$
$$\therefore \ 75.0\ \text{W} = 75000 \ \text{mW}$$
Example 3
Convert $110.0\ \text{W}$ to $\text{mW}$.
$$\text{Power}_{\text{mW}} = 110.0 \cdot {10}^{3}$$
$$\text{Power}_{\text{mW}} = 110000$$
$$\therefore \ 110.0\ \text{W} = 110000 \ \text{mW}$$
Example 4
Convert $150.0\ \text{W}$ to $\text{mW}$.
$$\text{Power}_{\text{mW}} = 150.0 \cdot {10}^{3}$$
$$\text{Power}_{\text{mW}} = 150000$$
$$\therefore \ 150.0\ \text{W} = 150000 \ \text{mW}$$
Example 5
Convert $200.0\ \text{W}$ to $\text{mW}$.
$$\text{Power}_{\text{mW}} = 200.0 \cdot {10}^{3}$$
$$\text{Power}_{\text{mW}} = 200000$$
$$\therefore \ 200.0\ \text{W} = 200000 \ \text{mW}$$
