How to convert Attogram to Carat
$$\text{Mass}_{\text{ct}} = \frac{\text{Mass}_{\text{ag}}}{200000000000000000}$$
Examples
Example 1
Convert $40.0\ \text{ag}$ to $\text{ct}$.
$$\text{Mass}_{\text{ct}} = \frac{40.0}{200000000000000000}$$
$$\text{Mass}_{\text{ct}} = 0.0000000000000002$$
$$\therefore \ 40.0\ \text{ag} = 0.0000000000000002 \ \text{ct}$$
Example 2
Convert $75.0\ \text{ag}$ to $\text{ct}$.
$$\text{Mass}_{\text{ct}} = \frac{75.0}{200000000000000000}$$
$$\text{Mass}_{\text{ct}} = 0.000000000000000375$$
$$\therefore \ 75.0\ \text{ag} = 0.000000000000000375 \ \text{ct}$$
Example 3
Convert $100.0\ \text{ag}$ to $\text{ct}$.
$$\text{Mass}_{\text{ct}} = \frac{100.0}{200000000000000000}$$
$$\text{Mass}_{\text{ct}} = 0.0000000000000005$$
$$\therefore \ 100.0\ \text{ag} = 0.0000000000000005 \ \text{ct}$$
Example 4
Convert $145.0\ \text{ag}$ to $\text{ct}$.
$$\text{Mass}_{\text{ct}} = \frac{145.0}{200000000000000000}$$
$$\text{Mass}_{\text{ct}} = 0.000000000000000725$$
$$\therefore \ 145.0\ \text{ag} = 0.000000000000000725 \ \text{ct}$$
Example 5
Convert $165.0\ \text{ag}$ to $\text{ct}$.
$$\text{Mass}_{\text{ct}} = \frac{165.0}{200000000000000000}$$
$$\text{Mass}_{\text{ct}} = 0.000000000000000825$$
$$\therefore \ 165.0\ \text{ag} = 0.000000000000000825 \ \text{ct}$$
