How to convert US beer barrel to US oil barrel
$$\text{Volume}_{\text{bbl (oil)}} = \text{Volume}_{\text{bbl (beer)}} \cdot 0.7380952380952380952380952380952381$$
Examples
Example 1
Convert $50.0\ \text{bbl (beer)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 50.0 \cdot 0.7380952380952380952380952380952381$$
$$\text{Volume}_{\text{bbl (oil)}} = 36.904762$$
$$\therefore \ 50.0\ \text{bbl (beer)} = 36.904762 \ \text{bbl (oil)}$$
Example 2
Convert $60.0\ \text{bbl (beer)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 60.0 \cdot 0.7380952380952380952380952380952381$$
$$\text{Volume}_{\text{bbl (oil)}} = 44.285714$$
$$\therefore \ 60.0\ \text{bbl (beer)} = 44.285714 \ \text{bbl (oil)}$$
Example 3
Convert $105.0\ \text{bbl (beer)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 105.0 \cdot 0.7380952380952380952380952380952381$$
$$\text{Volume}_{\text{bbl (oil)}} = 77.5$$
$$\therefore \ 105.0\ \text{bbl (beer)} = 77.5 \ \text{bbl (oil)}$$
Example 4
Convert $140.0\ \text{bbl (beer)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 140.0 \cdot 0.7380952380952380952380952380952381$$
$$\text{Volume}_{\text{bbl (oil)}} = 103.333333$$
$$\therefore \ 140.0\ \text{bbl (beer)} = 103.333333 \ \text{bbl (oil)}$$
Example 5
Convert $185.0\ \text{bbl (beer)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 185.0 \cdot 0.7380952380952380952380952380952381$$
$$\text{Volume}_{\text{bbl (oil)}} = 136.547619$$
$$\therefore \ 185.0\ \text{bbl (beer)} = 136.547619 \ \text{bbl (oil)}$$
