Convert Watt to Yoctowatt
Unit definitions
Watt
The watt is the SI unit of power. It is defined as one joule per second ($1\ \text{W} = 1\ \text{J/s}$).
Yoctowatt
$10^{-24}$ watts is a yoctowatt.
How to convert Watt to Yoctowatt
$$\text{Power}_{\text{yW}} = \text{Power}_{\text{W}} \cdot {10}^{24}$$
Examples
Example 1
Convert $20.0\ \text{W}$ to $\text{yW}$.
$$\text{Power}_{\text{yW}} = 20.0 \cdot {10}^{24}$$
$$\text{Power}_{\text{yW}} = 20000000000000000000000000$$
$$\therefore \ 20.0\ \text{W} = 20000000000000000000000000 \ \text{yW}$$
Example 2
Convert $90.0\ \text{W}$ to $\text{yW}$.
$$\text{Power}_{\text{yW}} = 90.0 \cdot {10}^{24}$$
$$\text{Power}_{\text{yW}} = 90000000000000000000000000$$
$$\therefore \ 90.0\ \text{W} = 90000000000000000000000000 \ \text{yW}$$
Example 3
Convert $110.0\ \text{W}$ to $\text{yW}$.
$$\text{Power}_{\text{yW}} = 110.0 \cdot {10}^{24}$$
$$\text{Power}_{\text{yW}} = 110000000000000000000000000$$
$$\therefore \ 110.0\ \text{W} = 110000000000000000000000000 \ \text{yW}$$
Example 4
Convert $130.0\ \text{W}$ to $\text{yW}$.
$$\text{Power}_{\text{yW}} = 130.0 \cdot {10}^{24}$$
$$\text{Power}_{\text{yW}} = 130000000000000000000000000$$
$$\therefore \ 130.0\ \text{W} = 130000000000000000000000000 \ \text{yW}$$
Example 5
Convert $175.0\ \text{W}$ to $\text{yW}$.
$$\text{Power}_{\text{yW}} = 175.0 \cdot {10}^{24}$$
$$\text{Power}_{\text{yW}} = 175000000000000000000000000$$
$$\therefore \ 175.0\ \text{W} = 175000000000000000000000000 \ \text{yW}$$
