Convert Watt to Zeptowatt
Unit definitions
Watt
The watt is the SI unit of power. It is defined as one joule per second ($1\ \text{W} = 1\ \text{J/s}$).
Zeptowatt
$10^{-21}$ watts is a zeptowatt.
How to convert Watt to Zeptowatt
$$\text{Power}_{\text{zW}} = \text{Power}_{\text{W}} \cdot {10}^{21}$$
Examples
Example 1
Convert $50.0\ \text{W}$ to $\text{zW}$.
$$\text{Power}_{\text{zW}} = 50.0 \cdot {10}^{21}$$
$$\text{Power}_{\text{zW}} = 50000000000000000000000$$
$$\therefore \ 50.0\ \text{W} = 50000000000000000000000 \ \text{zW}$$
Example 2
Convert $70.0\ \text{W}$ to $\text{zW}$.
$$\text{Power}_{\text{zW}} = 70.0 \cdot {10}^{21}$$
$$\text{Power}_{\text{zW}} = 70000000000000000000000$$
$$\therefore \ 70.0\ \text{W} = 70000000000000000000000 \ \text{zW}$$
Example 3
Convert $110.0\ \text{W}$ to $\text{zW}$.
$$\text{Power}_{\text{zW}} = 110.0 \cdot {10}^{21}$$
$$\text{Power}_{\text{zW}} = 110000000000000000000000$$
$$\therefore \ 110.0\ \text{W} = 110000000000000000000000 \ \text{zW}$$
Example 4
Convert $150.0\ \text{W}$ to $\text{zW}$.
$$\text{Power}_{\text{zW}} = 150.0 \cdot {10}^{21}$$
$$\text{Power}_{\text{zW}} = 150000000000000000000000$$
$$\therefore \ 150.0\ \text{W} = 150000000000000000000000 \ \text{zW}$$
Example 5
Convert $165.0\ \text{W}$ to $\text{zW}$.
$$\text{Power}_{\text{zW}} = 165.0 \cdot {10}^{21}$$
$$\text{Power}_{\text{zW}} = 165000000000000000000000$$
$$\therefore \ 165.0\ \text{W} = 165000000000000000000000 \ \text{zW}$$
