How to convert Petawatt to Nanowatt
$$\text{Power}_{\text{nW}} = \text{Power}_{\text{PW}} \cdot {10}^{24}$$
Examples
Example 1
Convert $40.0\ \text{PW}$ to $\text{nW}$.
$$\text{Power}_{\text{nW}} = 40.0 \cdot {10}^{24}$$
$$\text{Power}_{\text{nW}} = 40000000000000000000000000$$
$$\therefore \ 40.0\ \text{PW} = 40000000000000000000000000 \ \text{nW}$$
Example 2
Convert $90.0\ \text{PW}$ to $\text{nW}$.
$$\text{Power}_{\text{nW}} = 90.0 \cdot {10}^{24}$$
$$\text{Power}_{\text{nW}} = 90000000000000000000000000$$
$$\therefore \ 90.0\ \text{PW} = 90000000000000000000000000 \ \text{nW}$$
Example 3
Convert $105.0\ \text{PW}$ to $\text{nW}$.
$$\text{Power}_{\text{nW}} = 105.0 \cdot {10}^{24}$$
$$\text{Power}_{\text{nW}} = 105000000000000000000000000$$
$$\therefore \ 105.0\ \text{PW} = 105000000000000000000000000 \ \text{nW}$$
Example 4
Convert $150.0\ \text{PW}$ to $\text{nW}$.
$$\text{Power}_{\text{nW}} = 150.0 \cdot {10}^{24}$$
$$\text{Power}_{\text{nW}} = 150000000000000000000000000$$
$$\therefore \ 150.0\ \text{PW} = 150000000000000000000000000 \ \text{nW}$$
Example 5
Convert $200.0\ \text{PW}$ to $\text{nW}$.
$$\text{Power}_{\text{nW}} = 200.0 \cdot {10}^{24}$$
$$\text{Power}_{\text{nW}} = 200000000000000000000000000$$
$$\therefore \ 200.0\ \text{PW} = 200000000000000000000000000 \ \text{nW}$$
