$$\text{Volume}_{\text{gal (uk)}} = \text{Volume}_{\text{gal (liquid) (us)}} \cdot 0.8326741846289888673563435831670732$$
Examples
Example 1
Convert $45.0\ \text{gal (liquid) (us)}$ to $\text{gal (uk)}$.
$$\text{Volume}_{\text{gal (uk)}} = 45.0 \cdot 0.8326741846289888673563435831670732$$
$$\text{Volume}_{\text{gal (uk)}} = 37.470338$$
$$\therefore \ 45.0\ \text{gal (liquid) (us)} = 37.470338 \ \text{gal (uk)}$$
Example 2
Convert $90.0\ \text{gal (liquid) (us)}$ to $\text{gal (uk)}$.
$$\text{Volume}_{\text{gal (uk)}} = 90.0 \cdot 0.8326741846289888673563435831670732$$
$$\text{Volume}_{\text{gal (uk)}} = 74.940677$$
$$\therefore \ 90.0\ \text{gal (liquid) (us)} = 74.940677 \ \text{gal (uk)}$$
Example 3

$$\text{Volume}_{\text{gal (uk)}} = 108.247644$$
$$\therefore \ 130.0\ \text{gal (liquid) (us)} = 108.247644 \ \text{gal (uk)}$$
Example 5
Convert $190.0\ \text{gal (liquid) (us)}$ to $\text{gal (uk)}$.
$$\text{Volume}_{\text{gal (uk)}} = 190.0 \cdot 0.8326741846289888673563435831670732$$
$$\text{Volume}_{\text{gal (uk)}} = 158.208095$$
$$\therefore \ 190.0\ \text{gal (liquid) (us)} = 158.208095 \ \text{gal (uk)}$$
