How to convert Nanogram to Zeptogram
$$\text{Mass}_{\text{zg}} = \text{Mass}_{\text{ng}} \cdot 1000000000000$$
Examples
Example 1
Convert $40.0\ \text{ng}$ to $\text{zg}$.
$$\text{Mass}_{\text{zg}} = 40.0 \cdot 1000000000000$$
$$\text{Mass}_{\text{zg}} = 40000000000000$$
$$\therefore \ 40.0\ \text{ng} = 40000000000000 \ \text{zg}$$
Example 2
Convert $80.0\ \text{ng}$ to $\text{zg}$.
$$\text{Mass}_{\text{zg}} = 80.0 \cdot 1000000000000$$
$$\text{Mass}_{\text{zg}} = 80000000000000$$
$$\therefore \ 80.0\ \text{ng} = 80000000000000 \ \text{zg}$$
Example 3
Convert $100.0\ \text{ng}$ to $\text{zg}$.
$$\text{Mass}_{\text{zg}} = 100.0 \cdot 1000000000000$$
$$\text{Mass}_{\text{zg}} = 100000000000000$$
$$\therefore \ 100.0\ \text{ng} = 100000000000000 \ \text{zg}$$
Example 4
Convert $130.0\ \text{ng}$ to $\text{zg}$.
$$\text{Mass}_{\text{zg}} = 130.0 \cdot 1000000000000$$
$$\text{Mass}_{\text{zg}} = 130000000000000$$
$$\therefore \ 130.0\ \text{ng} = 130000000000000 \ \text{zg}$$
Example 5
Convert $195.0\ \text{ng}$ to $\text{zg}$.
$$\text{Mass}_{\text{zg}} = 195.0 \cdot 1000000000000$$
$$\text{Mass}_{\text{zg}} = 195000000000000$$
$$\therefore \ 195.0\ \text{ng} = 195000000000000 \ \text{zg}$$
