How to convert US liquid gallon to Liter
$$\text{Volume}_{\text{l}} = \text{Volume}_{\text{gal (liquid) (us)}} \cdot 3.785411784$$
Examples
Example 1
Convert $40.0\ \text{gal (liquid) (us)}$ to $\text{l}$.
$$\text{Volume}_{\text{l}} = 40.0 \cdot 3.785411784$$
$$\text{Volume}_{\text{l}} = 151.416471$$
$$\therefore \ 40.0\ \text{gal (liquid) (us)} = 151.416471 \ \text{l}$$
Example 2
Convert $80.0\ \text{gal (liquid) (us)}$ to $\text{l}$.
$$\text{Volume}_{\text{l}} = 80.0 \cdot 3.785411784$$
$$\text{Volume}_{\text{l}} = 302.832943$$
$$\therefore \ 80.0\ \text{gal (liquid) (us)} = 302.832943 \ \text{l}$$
Example 3
Convert $105.0\ \text{gal (liquid) (us)}$ to $\text{l}$.
$$\text{Volume}_{\text{l}} = 105.0 \cdot 3.785411784$$
$$\text{Volume}_{\text{l}} = 397.468237$$
$$\therefore \ 105.0\ \text{gal (liquid) (us)} = 397.468237 \ \text{l}$$
Example 4
Convert $140.0\ \text{gal (liquid) (us)}$ to $\text{l}$.
$$\text{Volume}_{\text{l}} = 140.0 \cdot 3.785411784$$
$$\text{Volume}_{\text{l}} = 529.95765$$
$$\therefore \ 140.0\ \text{gal (liquid) (us)} = 529.95765 \ \text{l}$$
Example 5
Convert $160.0\ \text{gal (liquid) (us)}$ to $\text{l}$.
$$\text{Volume}_{\text{l}} = 160.0 \cdot 3.785411784$$
$$\text{Volume}_{\text{l}} = 605.665885$$
$$\therefore \ 160.0\ \text{gal (liquid) (us)} = 605.665885 \ \text{l}$$
