How to convert US liquid gallon to US cup
$$\text{Volume}_{\text{cup (us)}} = \text{Volume}_{\text{gal (liquid) (us)}} \cdot 16$$
Examples
Example 1
Convert $40.0\ \text{gal (liquid) (us)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 40.0 \cdot 16$$
$$\text{Volume}_{\text{cup (us)}} = 640$$
$$\therefore \ 40.0\ \text{gal (liquid) (us)} = 640 \ \text{cup (us)}$$
Example 2
Convert $75.0\ \text{gal (liquid) (us)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 75.0 \cdot 16$$
$$\text{Volume}_{\text{cup (us)}} = 1200$$
$$\therefore \ 75.0\ \text{gal (liquid) (us)} = 1200 \ \text{cup (us)}$$
Example 3
Convert $115.0\ \text{gal (liquid) (us)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 115.0 \cdot 16$$
$$\text{Volume}_{\text{cup (us)}} = 1840$$
$$\therefore \ 115.0\ \text{gal (liquid) (us)} = 1840 \ \text{cup (us)}$$
Example 4
Convert $135.0\ \text{gal (liquid) (us)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 135.0 \cdot 16$$
$$\text{Volume}_{\text{cup (us)}} = 2160$$
$$\therefore \ 135.0\ \text{gal (liquid) (us)} = 2160 \ \text{cup (us)}$$
Example 5
Convert $195.0\ \text{gal (liquid) (us)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 195.0 \cdot 16$$
$$\text{Volume}_{\text{cup (us)}} = 3120$$
$$\therefore \ 195.0\ \text{gal (liquid) (us)} = 3120 \ \text{cup (us)}$$
