How to convert Fluid drachm (UK) to US dry barrel
$$\text{Volume}_{\text{bbl (dry) (us)}} = \text{Volume}_{\text{fl drc}} \cdot 0.00009214878054334286396356819710264842$$
Examples
Example 1
Convert $20.0\ \text{fl drc}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 20.0 \cdot 0.00009214878054334286396356819710264842$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.001843$$
$$\therefore \ 20.0\ \text{fl drc} = 0.001843 \ \text{bbl (dry) (us)}$$
Example 2
Convert $60.0\ \text{fl drc}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 60.0 \cdot 0.00009214878054334286396356819710264842$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.005529$$
$$\therefore \ 60.0\ \text{fl drc} = 0.005529 \ \text{bbl (dry) (us)}$$
Example 3
Convert $115.0\ \text{fl drc}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 115.0 \cdot 0.00009214878054334286396356819710264842$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.010597$$
$$\therefore \ 115.0\ \text{fl drc} = 0.010597 \ \text{bbl (dry) (us)}$$
Example 4
Convert $145.0\ \text{fl drc}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 145.0 \cdot 0.00009214878054334286396356819710264842$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.013362$$
$$\therefore \ 145.0\ \text{fl drc} = 0.013362 \ \text{bbl (dry) (us)}$$
Example 5
Convert $195.0\ \text{fl drc}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 195.0 \cdot 0.00009214878054334286396356819710264842$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.017969$$
$$\therefore \ 195.0\ \text{fl drc} = 0.017969 \ \text{bbl (dry) (us)}$$
