How to convert US liquid gallon to US barrel
$$\text{Volume}_{\text{bbl (US)}} = \text{Volume}_{\text{gal (liquid) (us)}} \cdot 0.03174603174603174603174603174603175$$
Examples
Example 1
Convert $35.0\ \text{gal (liquid) (us)}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 35.0 \cdot 0.03174603174603174603174603174603175$$
$$\text{Volume}_{\text{bbl (US)}} = 1.111111$$
$$\therefore \ 35.0\ \text{gal (liquid) (us)} = 1.111111 \ \text{bbl (US)}$$
Example 2
Convert $90.0\ \text{gal (liquid) (us)}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 90.0 \cdot 0.03174603174603174603174603174603175$$
$$\text{Volume}_{\text{bbl (US)}} = 2.857143$$
$$\therefore \ 90.0\ \text{gal (liquid) (us)} = 2.857143 \ \text{bbl (US)}$$
Example 3
Convert $110.0\ \text{gal (liquid) (us)}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 110.0 \cdot 0.03174603174603174603174603174603175$$
$$\text{Volume}_{\text{bbl (US)}} = 3.492063$$
$$\therefore \ 110.0\ \text{gal (liquid) (us)} = 3.492063 \ \text{bbl (US)}$$
Example 4
Convert $140.0\ \text{gal (liquid) (us)}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 140.0 \cdot 0.03174603174603174603174603174603175$$
$$\text{Volume}_{\text{bbl (US)}} = 4.444444$$
$$\therefore \ 140.0\ \text{gal (liquid) (us)} = 4.444444 \ \text{bbl (US)}$$
Example 5
Convert $190.0\ \text{gal (liquid) (us)}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 190.0 \cdot 0.03174603174603174603174603174603175$$
$$\text{Volume}_{\text{bbl (US)}} = 6.031746$$
$$\therefore \ 190.0\ \text{gal (liquid) (us)} = 6.031746 \ \text{bbl (US)}$$
