How to convert Femtowatt to Milliwatt
$$\text{Power}_{\text{mW}} = \frac{\text{Power}_{\text{fW}}}{{10}^{12}}$$
Examples
Example 1
Convert $20.0\ \text{fW}$ to $\text{mW}$.
$$\text{Power}_{\text{mW}} = \frac{20.0}{{10}^{12}}$$
$$\text{Power}_{\text{mW}} = 0.00000000002$$
$$\therefore \ 20.0\ \text{fW} = 0.00000000002 \ \text{mW}$$
Example 2
Convert $75.0\ \text{fW}$ to $\text{mW}$.
$$\text{Power}_{\text{mW}} = \frac{75.0}{{10}^{12}}$$
$$\text{Power}_{\text{mW}} = 0.000000000075$$
$$\therefore \ 75.0\ \text{fW} = 0.000000000075 \ \text{mW}$$
Example 3
Convert $110.0\ \text{fW}$ to $\text{mW}$.
$$\text{Power}_{\text{mW}} = \frac{110.0}{{10}^{12}}$$
$$\text{Power}_{\text{mW}} = 0.00000000011$$
$$\therefore \ 110.0\ \text{fW} = 0.00000000011 \ \text{mW}$$
Example 4
Convert $130.0\ \text{fW}$ to $\text{mW}$.
$$\text{Power}_{\text{mW}} = \frac{130.0}{{10}^{12}}$$
$$\text{Power}_{\text{mW}} = 0.00000000013$$
$$\therefore \ 130.0\ \text{fW} = 0.00000000013 \ \text{mW}$$
Example 5
Convert $180.0\ \text{fW}$ to $\text{mW}$.
$$\text{Power}_{\text{mW}} = \frac{180.0}{{10}^{12}}$$
$$\text{Power}_{\text{mW}} = 0.00000000018$$
$$\therefore \ 180.0\ \text{fW} = 0.00000000018 \ \text{mW}$$
