Convert Femtowatt to Watt
Unit definitions
Femtowatt
$10^{-15}$ watts is a femtowatt.
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 Femtowatt to Watt
$$\text{Power}_{\text{W}} = \frac{\text{Power}_{\text{fW}}}{{10}^{15}}$$
Examples
Example 1
Convert $35.0\ \text{fW}$ to $\text{W}$.
$$\text{Power}_{\text{W}} = \frac{35.0}{{10}^{15}}$$
$$\text{Power}_{\text{W}} = 0.000000000000035$$
$$\therefore \ 35.0\ \text{fW} = 0.000000000000035 \ \text{W}$$
Example 2
Convert $75.0\ \text{fW}$ to $\text{W}$.
$$\text{Power}_{\text{W}} = \frac{75.0}{{10}^{15}}$$
$$\text{Power}_{\text{W}} = 0.000000000000075$$
$$\therefore \ 75.0\ \text{fW} = 0.000000000000075 \ \text{W}$$
Example 3
Convert $115.0\ \text{fW}$ to $\text{W}$.
$$\text{Power}_{\text{W}} = \frac{115.0}{{10}^{15}}$$
$$\text{Power}_{\text{W}} = 0.000000000000115$$
$$\therefore \ 115.0\ \text{fW} = 0.000000000000115 \ \text{W}$$
Example 4
Convert $135.0\ \text{fW}$ to $\text{W}$.
$$\text{Power}_{\text{W}} = \frac{135.0}{{10}^{15}}$$
$$\text{Power}_{\text{W}} = 0.000000000000135$$
$$\therefore \ 135.0\ \text{fW} = 0.000000000000135 \ \text{W}$$
Example 5
Convert $160.0\ \text{fW}$ to $\text{W}$.
$$\text{Power}_{\text{W}} = \frac{160.0}{{10}^{15}}$$
$$\text{Power}_{\text{W}} = 0.00000000000016$$
$$\therefore \ 160.0\ \text{fW} = 0.00000000000016 \ \text{W}$$
