How to convert US cup to US dry barrel
$$\text{Volume}_{\text{bbl (dry) (us)}} = \text{Volume}_{\text{cup (us)}} \cdot 0.002046130952380952380952380952380952$$
Examples
Example 1
Convert $30.0\ \text{cup (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 30.0 \cdot 0.002046130952380952380952380952380952$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.061384$$
$$\therefore \ 30.0\ \text{cup (us)} = 0.061384 \ \text{bbl (dry) (us)}$$
Example 2
Convert $65.0\ \text{cup (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 65.0 \cdot 0.002046130952380952380952380952380952$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.132999$$
$$\therefore \ 65.0\ \text{cup (us)} = 0.132999 \ \text{bbl (dry) (us)}$$
Example 3
Convert $115.0\ \text{cup (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 115.0 \cdot 0.002046130952380952380952380952380952$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.235305$$
$$\therefore \ 115.0\ \text{cup (us)} = 0.235305 \ \text{bbl (dry) (us)}$$
Example 4
Convert $135.0\ \text{cup (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 135.0 \cdot 0.002046130952380952380952380952380952$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.276228$$
$$\therefore \ 135.0\ \text{cup (us)} = 0.276228 \ \text{bbl (dry) (us)}$$
Example 5
Convert $200.0\ \text{cup (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 200.0 \cdot 0.002046130952380952380952380952380952$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.409226$$
$$\therefore \ 200.0\ \text{cup (us)} = 0.409226 \ \text{bbl (dry) (us)}$$
