How to convert US fluid ounce to US dry gallon
$$\text{Volume}_{\text{gal (dry) (us)}} = \text{Volume}_{\text{oz (us)}} \cdot 0.006713804745119558039824778415379321$$
Examples
Example 1
Convert $40.0\ \text{oz (us)}$ to $\text{gal (dry) (us)}$.
$$\text{Volume}_{\text{gal (dry) (us)}} = 40.0 \cdot 0.006713804745119558039824778415379321$$
$$\text{Volume}_{\text{gal (dry) (us)}} = 0.268552$$
$$\therefore \ 40.0\ \text{oz (us)} = 0.268552 \ \text{gal (dry) (us)}$$
Example 2
Convert $70.0\ \text{oz (us)}$ to $\text{gal (dry) (us)}$.
$$\text{Volume}_{\text{gal (dry) (us)}} = 70.0 \cdot 0.006713804745119558039824778415379321$$
$$\text{Volume}_{\text{gal (dry) (us)}} = 0.469966$$
$$\therefore \ 70.0\ \text{oz (us)} = 0.469966 \ \text{gal (dry) (us)}$$
Example 3
Convert $115.0\ \text{oz (us)}$ to $\text{gal (dry) (us)}$.
$$\text{Volume}_{\text{gal (dry) (us)}} = 115.0 \cdot 0.006713804745119558039824778415379321$$
$$\text{Volume}_{\text{gal (dry) (us)}} = 0.772088$$
$$\therefore \ 115.0\ \text{oz (us)} = 0.772088 \ \text{gal (dry) (us)}$$
Example 4
Convert $135.0\ \text{oz (us)}$ to $\text{gal (dry) (us)}$.
$$\text{Volume}_{\text{gal (dry) (us)}} = 135.0 \cdot 0.006713804745119558039824778415379321$$
$$\text{Volume}_{\text{gal (dry) (us)}} = 0.906364$$
$$\therefore \ 135.0\ \text{oz (us)} = 0.906364 \ \text{gal (dry) (us)}$$
Example 5
Convert $185.0\ \text{oz (us)}$ to $\text{gal (dry) (us)}$.
$$\text{Volume}_{\text{gal (dry) (us)}} = 185.0 \cdot 0.006713804745119558039824778415379321$$
$$\text{Volume}_{\text{gal (dry) (us)}} = 1.242054$$
$$\therefore \ 185.0\ \text{oz (us)} = 1.242054 \ \text{gal (dry) (us)}$$
