How to convert US fluid ounce to Fluid dram (US)
$$\text{Volume}_{\text{fl dr}} = \text{Volume}_{\text{oz (us)}} \cdot 7.999999989855793202310217310009557$$
Examples
Example 1
Convert $30.0\ \text{oz (us)}$ to $\text{fl dr}$.
$$\text{Volume}_{\text{fl dr}} = 30.0 \cdot 7.999999989855793202310217310009557$$
$$\text{Volume}_{\text{fl dr}} = 240$$
$$\therefore \ 30.0\ \text{oz (us)} = 240 \ \text{fl dr}$$
Example 2
Convert $80.0\ \text{oz (us)}$ to $\text{fl dr}$.
$$\text{Volume}_{\text{fl dr}} = 80.0 \cdot 7.999999989855793202310217310009557$$
$$\text{Volume}_{\text{fl dr}} = 639.999999$$
$$\therefore \ 80.0\ \text{oz (us)} = 639.999999 \ \text{fl dr}$$
Example 3
Convert $120.0\ \text{oz (us)}$ to $\text{fl dr}$.
$$\text{Volume}_{\text{fl dr}} = 120.0 \cdot 7.999999989855793202310217310009557$$
$$\text{Volume}_{\text{fl dr}} = 959.999999$$
$$\therefore \ 120.0\ \text{oz (us)} = 959.999999 \ \text{fl dr}$$
Example 4
Convert $130.0\ \text{oz (us)}$ to $\text{fl dr}$.
$$\text{Volume}_{\text{fl dr}} = 130.0 \cdot 7.999999989855793202310217310009557$$
$$\text{Volume}_{\text{fl dr}} = 1039.999999$$
$$\therefore \ 130.0\ \text{oz (us)} = 1039.999999 \ \text{fl dr}$$
Example 5
Convert $200.0\ \text{oz (us)}$ to $\text{fl dr}$.
$$\text{Volume}_{\text{fl dr}} = 200.0 \cdot 7.999999989855793202310217310009557$$
$$\text{Volume}_{\text{fl dr}} = 1599.999998$$
$$\therefore \ 200.0\ \text{oz (us)} = 1599.999998 \ \text{fl dr}$$
