How to convert UK pint to US liquid gallon
$$\text{Volume}_{\text{gal (liquid) (us)}} = \text{Volume}_{\text{pt (uk)}} \cdot 0.1501187406881068662093011543285247$$
Examples
Example 1
Convert $45.0\ \text{pt (uk)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 45.0 \cdot 0.1501187406881068662093011543285247$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 6.755343$$
$$\therefore \ 45.0\ \text{pt (uk)} = 6.755343 \ \text{gal (liquid) (us)}$$
Example 2
Convert $60.0\ \text{pt (uk)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 60.0 \cdot 0.1501187406881068662093011543285247$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 9.007124$$
$$\therefore \ 60.0\ \text{pt (uk)} = 9.007124 \ \text{gal (liquid) (us)}$$
Example 3
Convert $105.0\ \text{pt (uk)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 105.0 \cdot 0.1501187406881068662093011543285247$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 15.762468$$
$$\therefore \ 105.0\ \text{pt (uk)} = 15.762468 \ \text{gal (liquid) (us)}$$
Example 4
Convert $140.0\ \text{pt (uk)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 140.0 \cdot 0.1501187406881068662093011543285247$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 21.016624$$
$$\therefore \ 140.0\ \text{pt (uk)} = 21.016624 \ \text{gal (liquid) (us)}$$
Example 5
Convert $200.0\ \text{pt (uk)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 200.0 \cdot 0.1501187406881068662093011543285247$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 30.023748$$
$$\therefore \ 200.0\ \text{pt (uk)} = 30.023748 \ \text{gal (liquid) (us)}$$
