How to convert Quectogram to Zeptogram
$$\text{Mass}_{\text{zg}} = \frac{\text{Mass}_{\text{qg}}}{1000000000}$$
Examples
Example 1
Convert $20.0\ \text{qg}$ to $\text{zg}$.
$$\text{Mass}_{\text{zg}} = \frac{20.0}{1000000000}$$
$$\text{Mass}_{\text{zg}} = 0.00000002$$
$$\therefore \ 20.0\ \text{qg} = 0.00000002 \ \text{zg}$$
Example 2
Convert $75.0\ \text{qg}$ to $\text{zg}$.
$$\text{Mass}_{\text{zg}} = \frac{75.0}{1000000000}$$
$$\text{Mass}_{\text{zg}} = 0.000000075$$
$$\therefore \ 75.0\ \text{qg} = 0.000000075 \ \text{zg}$$
Example 3
Convert $120.0\ \text{qg}$ to $\text{zg}$.
$$\text{Mass}_{\text{zg}} = \frac{120.0}{1000000000}$$
$$\text{Mass}_{\text{zg}} = 0.00000012$$
$$\therefore \ 120.0\ \text{qg} = 0.00000012 \ \text{zg}$$
Example 4
Convert $140.0\ \text{qg}$ to $\text{zg}$.
$$\text{Mass}_{\text{zg}} = \frac{140.0}{1000000000}$$
$$\text{Mass}_{\text{zg}} = 0.00000014$$
$$\therefore \ 140.0\ \text{qg} = 0.00000014 \ \text{zg}$$
Example 5
Convert $165.0\ \text{qg}$ to $\text{zg}$.
$$\text{Mass}_{\text{zg}} = \frac{165.0}{1000000000}$$
$$\text{Mass}_{\text{zg}} = 0.000000165$$
$$\therefore \ 165.0\ \text{qg} = 0.000000165 \ \text{zg}$$
