How to convert UK gallon to US dry barrel
$$\text{Volume}_{\text{bbl (dry) (us)}} = \text{Volume}_{\text{gal (uk)}} \cdot 0.03931681303736132210243601660985171$$
Examples
Example 1
Convert $50.0\ \text{gal (uk)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 50.0 \cdot 0.03931681303736132210243601660985171$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 1.965841$$
$$\therefore \ 50.0\ \text{gal (uk)} = 1.965841 \ \text{bbl (dry) (us)}$$
Example 2
Convert $65.0\ \text{gal (uk)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 65.0 \cdot 0.03931681303736132210243601660985171$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 2.555593$$
$$\therefore \ 65.0\ \text{gal (uk)} = 2.555593 \ \text{bbl (dry) (us)}$$
Example 3
Convert $100.0\ \text{gal (uk)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 100.0 \cdot 0.03931681303736132210243601660985171$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 3.931681$$
$$\therefore \ 100.0\ \text{gal (uk)} = 3.931681 \ \text{bbl (dry) (us)}$$
Example 4
Convert $140.0\ \text{gal (uk)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 140.0 \cdot 0.03931681303736132210243601660985171$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 5.504354$$
$$\therefore \ 140.0\ \text{gal (uk)} = 5.504354 \ \text{bbl (dry) (us)}$$
Example 5
Convert $190.0\ \text{gal (uk)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 190.0 \cdot 0.03931681303736132210243601660985171$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 7.470194$$
$$\therefore \ 190.0\ \text{gal (uk)} = 7.470194 \ \text{bbl (dry) (us)}$$
