How to convert US dry gallon to US oil barrel
$$\text{Volume}_{\text{bbl (oil)}} = \text{Volume}_{\text{gal (dry) (us)}} \cdot 0.02770588538445681302824159967017110$$
Examples
Example 1
Convert $35.0\ \text{gal (dry) (us)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 35.0 \cdot 0.02770588538445681302824159967017110$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.969706$$
$$\therefore \ 35.0\ \text{gal (dry) (us)} = 0.969706 \ \text{bbl (oil)}$$
Example 2
Convert $85.0\ \text{gal (dry) (us)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 85.0 \cdot 0.02770588538445681302824159967017110$$
$$\text{Volume}_{\text{bbl (oil)}} = 2.355$$
$$\therefore \ 85.0\ \text{gal (dry) (us)} = 2.355 \ \text{bbl (oil)}$$
Example 3
Convert $100.0\ \text{gal (dry) (us)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 100.0 \cdot 0.02770588538445681302824159967017110$$
$$\text{Volume}_{\text{bbl (oil)}} = 2.770589$$
$$\therefore \ 100.0\ \text{gal (dry) (us)} = 2.770589 \ \text{bbl (oil)}$$
Example 4
Convert $140.0\ \text{gal (dry) (us)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 140.0 \cdot 0.02770588538445681302824159967017110$$
$$\text{Volume}_{\text{bbl (oil)}} = 3.878824$$
$$\therefore \ 140.0\ \text{gal (dry) (us)} = 3.878824 \ \text{bbl (oil)}$$
Example 5
Convert $180.0\ \text{gal (dry) (us)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 180.0 \cdot 0.02770588538445681302824159967017110$$
$$\text{Volume}_{\text{bbl (oil)}} = 4.987059$$
$$\therefore \ 180.0\ \text{gal (dry) (us)} = 4.987059 \ \text{bbl (oil)}$$
