How to convert US barrel to US fluid ounce
$$\text{Volume}_{\text{oz (us)}} = \text{Volume}_{\text{bbl (US)}} \cdot 4032$$
Examples
Example 1
Convert $25.0\ \text{bbl (US)}$ to $\text{oz (us)}$.
$$\text{Volume}_{\text{oz (us)}} = 25.0 \cdot 4032$$
$$\text{Volume}_{\text{oz (us)}} = 100800$$
$$\therefore \ 25.0\ \text{bbl (US)} = 100800 \ \text{oz (us)}$$
Example 2
Convert $70.0\ \text{bbl (US)}$ to $\text{oz (us)}$.
$$\text{Volume}_{\text{oz (us)}} = 70.0 \cdot 4032$$
$$\text{Volume}_{\text{oz (us)}} = 282240$$
$$\therefore \ 70.0\ \text{bbl (US)} = 282240 \ \text{oz (us)}$$
Example 3
Convert $100.0\ \text{bbl (US)}$ to $\text{oz (us)}$.
$$\text{Volume}_{\text{oz (us)}} = 100.0 \cdot 4032$$
$$\text{Volume}_{\text{oz (us)}} = 403200$$
$$\therefore \ 100.0\ \text{bbl (US)} = 403200 \ \text{oz (us)}$$
Example 4
Convert $145.0\ \text{bbl (US)}$ to $\text{oz (us)}$.
$$\text{Volume}_{\text{oz (us)}} = 145.0 \cdot 4032$$
$$\text{Volume}_{\text{oz (us)}} = 584640$$
$$\therefore \ 145.0\ \text{bbl (US)} = 584640 \ \text{oz (us)}$$
Example 5
Convert $160.0\ \text{bbl (US)}$ to $\text{oz (us)}$.
$$\text{Volume}_{\text{oz (us)}} = 160.0 \cdot 4032$$
$$\text{Volume}_{\text{oz (us)}} = 645120$$
$$\therefore \ 160.0\ \text{bbl (US)} = 645120 \ \text{oz (us)}$$
