How to convert Rontogram to Carat
$$\text{Mass}_{\text{ct}} = \frac{\text{Mass}_{\text{rg}}}{200000000000000000000000000}$$
Examples
Example 1
Convert $45.0\ \text{rg}$ to $\text{ct}$.
$$\text{Mass}_{\text{ct}} = \frac{45.0}{200000000000000000000000000}$$
$$\text{Mass}_{\text{ct}} = 0.000000000000000000000000225$$
$$\therefore \ 45.0\ \text{rg} = 0.000000000000000000000000225 \ \text{ct}$$
Example 2
Convert $85.0\ \text{rg}$ to $\text{ct}$.
$$\text{Mass}_{\text{ct}} = \frac{85.0}{200000000000000000000000000}$$
$$\text{Mass}_{\text{ct}} = 0.000000000000000000000000425$$
$$\therefore \ 85.0\ \text{rg} = 0.000000000000000000000000425 \ \text{ct}$$
Example 3
Convert $110.0\ \text{rg}$ to $\text{ct}$.
$$\text{Mass}_{\text{ct}} = \frac{110.0}{200000000000000000000000000}$$
$$\text{Mass}_{\text{ct}} = 0.00000000000000000000000055$$
$$\therefore \ 110.0\ \text{rg} = 0.00000000000000000000000055 \ \text{ct}$$
Example 4
Convert $130.0\ \text{rg}$ to $\text{ct}$.
$$\text{Mass}_{\text{ct}} = \frac{130.0}{200000000000000000000000000}$$
$$\text{Mass}_{\text{ct}} = 0.00000000000000000000000065$$
$$\therefore \ 130.0\ \text{rg} = 0.00000000000000000000000065 \ \text{ct}$$
Example 5
Convert $170.0\ \text{rg}$ to $\text{ct}$.
$$\text{Mass}_{\text{ct}} = \frac{170.0}{200000000000000000000000000}$$
$$\text{Mass}_{\text{ct}} = 0.00000000000000000000000085$$
$$\therefore \ 170.0\ \text{rg} = 0.00000000000000000000000085 \ \text{ct}$$
