How to convert US oil barrel to US cup
$$\text{Volume}_{\text{cup (us)}} = \text{Volume}_{\text{bbl (oil)}} \cdot 672$$
Examples
Example 1
Convert $20.0\ \text{bbl (oil)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 20.0 \cdot 672$$
$$\text{Volume}_{\text{cup (us)}} = 13440$$
$$\therefore \ 20.0\ \text{bbl (oil)} = 13440 \ \text{cup (us)}$$
Example 2
Convert $75.0\ \text{bbl (oil)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 75.0 \cdot 672$$
$$\text{Volume}_{\text{cup (us)}} = 50400$$
$$\therefore \ 75.0\ \text{bbl (oil)} = 50400 \ \text{cup (us)}$$
Example 3
Convert $105.0\ \text{bbl (oil)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 105.0 \cdot 672$$
$$\text{Volume}_{\text{cup (us)}} = 70560$$
$$\therefore \ 105.0\ \text{bbl (oil)} = 70560 \ \text{cup (us)}$$
Example 4
Convert $135.0\ \text{bbl (oil)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 135.0 \cdot 672$$
$$\text{Volume}_{\text{cup (us)}} = 90720$$
$$\therefore \ 135.0\ \text{bbl (oil)} = 90720 \ \text{cup (us)}$$
Example 5
Convert $180.0\ \text{bbl (oil)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 180.0 \cdot 672$$
$$\text{Volume}_{\text{cup (us)}} = 120960$$
$$\therefore \ 180.0\ \text{bbl (oil)} = 120960 \ \text{cup (us)}$$
