How to convert Rontogram to Microgram
$$\text{Mass}_{\text{μg}} = \frac{\text{Mass}_{\text{rg}}}{1000000000000000000000}$$
Examples
Example 1
Convert $40.0\ \text{rg}$ to $\text{μg}$.
$$\text{Mass}_{\text{μg}} = \frac{40.0}{1000000000000000000000}$$
$$\text{Mass}_{\text{μg}} = 0.00000000000000000004$$
$$\therefore \ 40.0\ \text{rg} = 0.00000000000000000004 \ \text{μg}$$
Example 2
Convert $60.0\ \text{rg}$ to $\text{μg}$.
$$\text{Mass}_{\text{μg}} = \frac{60.0}{1000000000000000000000}$$
$$\text{Mass}_{\text{μg}} = 0.00000000000000000006$$
$$\therefore \ 60.0\ \text{rg} = 0.00000000000000000006 \ \text{μg}$$
Example 3
Convert $110.0\ \text{rg}$ to $\text{μg}$.
$$\text{Mass}_{\text{μg}} = \frac{110.0}{1000000000000000000000}$$
$$\text{Mass}_{\text{μg}} = 0.00000000000000000011$$
$$\therefore \ 110.0\ \text{rg} = 0.00000000000000000011 \ \text{μg}$$
Example 4
Convert $150.0\ \text{rg}$ to $\text{μg}$.
$$\text{Mass}_{\text{μg}} = \frac{150.0}{1000000000000000000000}$$
$$\text{Mass}_{\text{μg}} = 0.00000000000000000015$$
$$\therefore \ 150.0\ \text{rg} = 0.00000000000000000015 \ \text{μg}$$
Example 5
Convert $195.0\ \text{rg}$ to $\text{μg}$.
$$\text{Mass}_{\text{μg}} = \frac{195.0}{1000000000000000000000}$$
$$\text{Mass}_{\text{μg}} = 0.000000000000000000195$$
$$\therefore \ 195.0\ \text{rg} = 0.000000000000000000195 \ \text{μg}$$
