How to convert US liquid gallon to Cubic inch
$$\text{Volume}_{\text{in³}} = \text{Volume}_{\text{gal (liquid) (us)}} \cdot 231$$
Examples
Example 1
Convert $20.0\ \text{gal (liquid) (us)}$ to $\text{in³}$.
$$\text{Volume}_{\text{in³}} = 20.0 \cdot 231$$
$$\text{Volume}_{\text{in³}} = 4620$$
$$\therefore \ 20.0\ \text{gal (liquid) (us)} = 4620 \ \text{in³}$$
Example 2
Convert $65.0\ \text{gal (liquid) (us)}$ to $\text{in³}$.
$$\text{Volume}_{\text{in³}} = 65.0 \cdot 231$$
$$\text{Volume}_{\text{in³}} = 15015$$
$$\therefore \ 65.0\ \text{gal (liquid) (us)} = 15015 \ \text{in³}$$
Example 3
Convert $110.0\ \text{gal (liquid) (us)}$ to $\text{in³}$.
$$\text{Volume}_{\text{in³}} = 110.0 \cdot 231$$
$$\text{Volume}_{\text{in³}} = 25410$$
$$\therefore \ 110.0\ \text{gal (liquid) (us)} = 25410 \ \text{in³}$$
Example 4
Convert $130.0\ \text{gal (liquid) (us)}$ to $\text{in³}$.
$$\text{Volume}_{\text{in³}} = 130.0 \cdot 231$$
$$\text{Volume}_{\text{in³}} = 30030$$
$$\therefore \ 130.0\ \text{gal (liquid) (us)} = 30030 \ \text{in³}$$
Example 5
Convert $200.0\ \text{gal (liquid) (us)}$ to $\text{in³}$.
$$\text{Volume}_{\text{in³}} = 200.0 \cdot 231$$
$$\text{Volume}_{\text{in³}} = 46200$$
$$\therefore \ 200.0\ \text{gal (liquid) (us)} = 46200 \ \text{in³}$$
