How to convert US liquid gallon to US quart
$$\text{Volume}_{\text{qt (us)}} = \text{Volume}_{\text{gal (liquid) (us)}} \cdot 4$$
Examples
Example 1
Convert $40.0\ \text{gal (liquid) (us)}$ to $\text{qt (us)}$.
$$\text{Volume}_{\text{qt (us)}} = 40.0 \cdot 4$$
$$\text{Volume}_{\text{qt (us)}} = 160$$
$$\therefore \ 40.0\ \text{gal (liquid) (us)} = 160 \ \text{qt (us)}$$
Example 2
Convert $90.0\ \text{gal (liquid) (us)}$ to $\text{qt (us)}$.
$$\text{Volume}_{\text{qt (us)}} = 90.0 \cdot 4$$
$$\text{Volume}_{\text{qt (us)}} = 360$$
$$\therefore \ 90.0\ \text{gal (liquid) (us)} = 360 \ \text{qt (us)}$$
Example 3
Convert $115.0\ \text{gal (liquid) (us)}$ to $\text{qt (us)}$.
$$\text{Volume}_{\text{qt (us)}} = 115.0 \cdot 4$$
$$\text{Volume}_{\text{qt (us)}} = 460$$
$$\therefore \ 115.0\ \text{gal (liquid) (us)} = 460 \ \text{qt (us)}$$
Example 4
Convert $130.0\ \text{gal (liquid) (us)}$ to $\text{qt (us)}$.
$$\text{Volume}_{\text{qt (us)}} = 130.0 \cdot 4$$
$$\text{Volume}_{\text{qt (us)}} = 520$$
$$\therefore \ 130.0\ \text{gal (liquid) (us)} = 520 \ \text{qt (us)}$$
Example 5
Convert $180.0\ \text{gal (liquid) (us)}$ to $\text{qt (us)}$.
$$\text{Volume}_{\text{qt (us)}} = 180.0 \cdot 4$$
$$\text{Volume}_{\text{qt (us)}} = 720$$
$$\therefore \ 180.0\ \text{gal (liquid) (us)} = 720 \ \text{qt (us)}$$
