Convert Watt to Zettawatt
Unit definitions
Watt
The watt is the SI unit of power. It is defined as one joule per second ($1\ \text{W} = 1\ \text{J/s}$).
Zettawatt
$10^{21}$ watts is a zettawatt.
How to convert Watt to Zettawatt
$$\text{Power}_{\text{ZW}} = \frac{\text{Power}_{\text{W}}}{{10}^{21}}$$
Examples
Example 1
Convert $30.0\ \text{W}$ to $\text{ZW}$.
$$\text{Power}_{\text{ZW}} = \frac{30.0}{{10}^{21}}$$
$$\text{Power}_{\text{ZW}} = 0.00000000000000000003$$
$$\therefore \ 30.0\ \text{W} = 0.00000000000000000003 \ \text{ZW}$$
Example 2
Convert $80.0\ \text{W}$ to $\text{ZW}$.
$$\text{Power}_{\text{ZW}} = \frac{80.0}{{10}^{21}}$$
$$\text{Power}_{\text{ZW}} = 0.00000000000000000008$$
$$\therefore \ 80.0\ \text{W} = 0.00000000000000000008 \ \text{ZW}$$
Example 3
Convert $100.0\ \text{W}$ to $\text{ZW}$.
$$\text{Power}_{\text{ZW}} = \frac{100.0}{{10}^{21}}$$
$$\text{Power}_{\text{ZW}} = 0.0000000000000000001$$
$$\therefore \ 100.0\ \text{W} = 0.0000000000000000001 \ \text{ZW}$$
Example 4
Convert $140.0\ \text{W}$ to $\text{ZW}$.
$$\text{Power}_{\text{ZW}} = \frac{140.0}{{10}^{21}}$$
$$\text{Power}_{\text{ZW}} = 0.00000000000000000014$$
$$\therefore \ 140.0\ \text{W} = 0.00000000000000000014 \ \text{ZW}$$
Example 5
Convert $170.0\ \text{W}$ to $\text{ZW}$.
$$\text{Power}_{\text{ZW}} = \frac{170.0}{{10}^{21}}$$
$$\text{Power}_{\text{ZW}} = 0.00000000000000000017$$
$$\therefore \ 170.0\ \text{W} = 0.00000000000000000017 \ \text{ZW}$$
