How to convert Rontogram to Femtogram
$$\text{Mass}_{\text{fg}} = \frac{\text{Mass}_{\text{rg}}}{1000000000000}$$
Examples
Example 1
Convert $25.0\ \text{rg}$ to $\text{fg}$.
$$\text{Mass}_{\text{fg}} = \frac{25.0}{1000000000000}$$
$$\text{Mass}_{\text{fg}} = 0.000000000025$$
$$\therefore \ 25.0\ \text{rg} = 0.000000000025 \ \text{fg}$$
Example 2
Convert $75.0\ \text{rg}$ to $\text{fg}$.
$$\text{Mass}_{\text{fg}} = \frac{75.0}{1000000000000}$$
$$\text{Mass}_{\text{fg}} = 0.000000000075$$
$$\therefore \ 75.0\ \text{rg} = 0.000000000075 \ \text{fg}$$
Example 3
Convert $115.0\ \text{rg}$ to $\text{fg}$.
$$\text{Mass}_{\text{fg}} = \frac{115.0}{1000000000000}$$
$$\text{Mass}_{\text{fg}} = 0.000000000115$$
$$\therefore \ 115.0\ \text{rg} = 0.000000000115 \ \text{fg}$$
Example 4
Convert $135.0\ \text{rg}$ to $\text{fg}$.
$$\text{Mass}_{\text{fg}} = \frac{135.0}{1000000000000}$$
$$\text{Mass}_{\text{fg}} = 0.000000000135$$
$$\therefore \ 135.0\ \text{rg} = 0.000000000135 \ \text{fg}$$
Example 5
Convert $160.0\ \text{rg}$ to $\text{fg}$.
$$\text{Mass}_{\text{fg}} = \frac{160.0}{1000000000000}$$
$$\text{Mass}_{\text{fg}} = 0.00000000016$$
$$\therefore \ 160.0\ \text{rg} = 0.00000000016 \ \text{fg}$$
