Convert Watt to Picowatt
Unit definitions
Watt
The watt is the SI unit of power. It is defined as one joule per second ($1\ \text{W} = 1\ \text{J/s}$).
Picowatt
$10^{-12}$ watts is a picowatt.
How to convert Watt to Picowatt
$$\text{Power}_{\text{pW}} = \text{Power}_{\text{W}} \cdot {10}^{12}$$
Examples
Example 1
Convert $20.0\ \text{W}$ to $\text{pW}$.
$$\text{Power}_{\text{pW}} = 20.0 \cdot {10}^{12}$$
$$\text{Power}_{\text{pW}} = 20000000000000$$
$$\therefore \ 20.0\ \text{W} = 20000000000000 \ \text{pW}$$
Example 2
Convert $70.0\ \text{W}$ to $\text{pW}$.
$$\text{Power}_{\text{pW}} = 70.0 \cdot {10}^{12}$$
$$\text{Power}_{\text{pW}} = 70000000000000$$
$$\therefore \ 70.0\ \text{W} = 70000000000000 \ \text{pW}$$
Example 3
Convert $105.0\ \text{W}$ to $\text{pW}$.
$$\text{Power}_{\text{pW}} = 105.0 \cdot {10}^{12}$$
$$\text{Power}_{\text{pW}} = 105000000000000$$
$$\therefore \ 105.0\ \text{W} = 105000000000000 \ \text{pW}$$
Example 4
Convert $135.0\ \text{W}$ to $\text{pW}$.
$$\text{Power}_{\text{pW}} = 135.0 \cdot {10}^{12}$$
$$\text{Power}_{\text{pW}} = 135000000000000$$
$$\therefore \ 135.0\ \text{W} = 135000000000000 \ \text{pW}$$
Example 5
Convert $190.0\ \text{W}$ to $\text{pW}$.
$$\text{Power}_{\text{pW}} = 190.0 \cdot {10}^{12}$$
$$\text{Power}_{\text{pW}} = 190000000000000$$
$$\therefore \ 190.0\ \text{W} = 190000000000000 \ \text{pW}$$
