How to convert Fluid drachm (UK) to US barrel
$$\text{Volume}_{\text{bbl (US)}} = \text{Volume}_{\text{fl drc}} \cdot 0.00008935639325415065596467219112984090$$
Examples
Example 1
Convert $20.0\ \text{fl drc}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 20.0 \cdot 0.00008935639325415065596467219112984090$$
$$\text{Volume}_{\text{bbl (US)}} = 0.001787$$
$$\therefore \ 20.0\ \text{fl drc} = 0.001787 \ \text{bbl (US)}$$
Example 2
Convert $75.0\ \text{fl drc}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 75.0 \cdot 0.00008935639325415065596467219112984090$$

$$\text{Volume}_{\text{bbl (US)}} = 0.01251$$
$$\therefore \ 140.0\ \text{fl drc} = 0.01251 \ \text{bbl (US)}$$
Example 5
Convert $200.0\ \text{fl drc}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 200.0 \cdot 0.00008935639325415065596467219112984090$$
$$\text{Volume}_{\text{bbl (US)}} = 0.017871$$
