How to convert US cup to US liquid gallon
$$\text{Volume}_{\text{gal (liquid) (us)}} = \frac{\text{Volume}_{\text{cup (us)}}}{16}$$
Examples
Example 1
Convert $20.0\ \text{cup (us)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = \frac{20.0}{16}$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 1.25$$
$$\therefore \ 20.0\ \text{cup (us)} = 1.25 \ \text{gal (liquid) (us)}$$
Example 2
Convert $85.0\ \text{cup (us)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = \frac{85.0}{16}$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 5.3125$$
$$\therefore \ 85.0\ \text{cup (us)} = 5.3125 \ \text{gal (liquid) (us)}$$
Example 3
Convert $120.0\ \text{cup (us)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = \frac{120.0}{16}$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 7.5$$
$$\therefore \ 120.0\ \text{cup (us)} = 7.5 \ \text{gal (liquid) (us)}$$
Example 4
Convert $140.0\ \text{cup (us)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = \frac{140.0}{16}$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 8.75$$
$$\therefore \ 140.0\ \text{cup (us)} = 8.75 \ \text{gal (liquid) (us)}$$
Example 5
Convert $200.0\ \text{cup (us)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = \frac{200.0}{16}$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 12.5$$
$$\therefore \ 200.0\ \text{cup (us)} = 12.5 \ \text{gal (liquid) (us)}$$
