Convert Watt to Petawatt
Unit definitions
Watt
The watt is the SI unit of power. It is defined as one joule per second ($1\ \text{W} = 1\ \text{J/s}$).
Petawatt
$10^{15}$ watts is a petawatt.
How to convert Watt to Petawatt
$$\text{Power}_{\text{PW}} = \frac{\text{Power}_{\text{W}}}{{10}^{15}}$$
Examples
Example 1
Convert $25.0\ \text{W}$ to $\text{PW}$.
$$\text{Power}_{\text{PW}} = \frac{25.0}{{10}^{15}}$$
$$\text{Power}_{\text{PW}} = 0.000000000000025$$
$$\therefore \ 25.0\ \text{W} = 0.000000000000025 \ \text{PW}$$
Example 2
Convert $85.0\ \text{W}$ to $\text{PW}$.
$$\text{Power}_{\text{PW}} = \frac{85.0}{{10}^{15}}$$
$$\text{Power}_{\text{PW}} = 0.000000000000085$$
$$\therefore \ 85.0\ \text{W} = 0.000000000000085 \ \text{PW}$$
Example 3
Convert $120.0\ \text{W}$ to $\text{PW}$.
$$\text{Power}_{\text{PW}} = \frac{120.0}{{10}^{15}}$$
$$\text{Power}_{\text{PW}} = 0.00000000000012$$
$$\therefore \ 120.0\ \text{W} = 0.00000000000012 \ \text{PW}$$
Example 4
Convert $135.0\ \text{W}$ to $\text{PW}$.
$$\text{Power}_{\text{PW}} = \frac{135.0}{{10}^{15}}$$
$$\text{Power}_{\text{PW}} = 0.000000000000135$$
$$\therefore \ 135.0\ \text{W} = 0.000000000000135 \ \text{PW}$$
Example 5
Convert $185.0\ \text{W}$ to $\text{PW}$.
$$\text{Power}_{\text{PW}} = \frac{185.0}{{10}^{15}}$$
$$\text{Power}_{\text{PW}} = 0.000000000000185$$
$$\therefore \ 185.0\ \text{W} = 0.000000000000185 \ \text{PW}$$
