How to convert Fluid drachm (UK) to US liquid gallon
$$\text{Volume}_{\text{gal (liquid) (us)}} = \text{Volume}_{\text{fl drc}} \cdot 0.002814726387505745662887174020589988$$
Examples
Example 1
Convert $20.0\ \text{fl drc}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 20.0 \cdot 0.002814726387505745662887174020589988$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 0.056295$$
$$\therefore \ 20.0\ \text{fl drc} = 0.056295 \ \text{gal (liquid) (us)}$$
Example 2
Convert $70.0\ \text{fl drc}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 70.0 \cdot 0.002814726387505745662887174020589988$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 0.197031$$
$$\therefore \ 70.0\ \text{fl drc} = 0.197031 \ \text{gal (liquid) (us)}$$
Example 3
Convert $115.0\ \text{fl drc}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 115.0 \cdot 0.002814726387505745662887174020589988$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 0.323694$$
$$\therefore \ 115.0\ \text{fl drc} = 0.323694 \ \text{gal (liquid) (us)}$$
Example 4
Convert $135.0\ \text{fl drc}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 135.0 \cdot 0.002814726387505745662887174020589988$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 0.379988$$
$$\therefore \ 135.0\ \text{fl drc} = 0.379988 \ \text{gal (liquid) (us)}$$
Example 5
Convert $190.0\ \text{fl drc}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 190.0 \cdot 0.002814726387505745662887174020589988$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 0.534798$$
$$\therefore \ 190.0\ \text{fl drc} = 0.534798 \ \text{gal (liquid) (us)}$$
