How to convert US fluid ounce to US dry barrel
$$\text{Volume}_{\text{bbl (dry) (us)}} = \text{Volume}_{\text{oz (us)}} \cdot 0.0002557663690476190476190476190476190$$
Examples
Example 1
Convert $45.0\ \text{oz (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 45.0 \cdot 0.0002557663690476190476190476190476190$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.011509$$
$$\therefore \ 45.0\ \text{oz (us)} = 0.011509 \ \text{bbl (dry) (us)}$$
Example 2
Convert $85.0\ \text{oz (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 85.0 \cdot 0.0002557663690476190476190476190476190$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.02174$$
$$\therefore \ 85.0\ \text{oz (us)} = 0.02174 \ \text{bbl (dry) (us)}$$
Example 3
Convert $100.0\ \text{oz (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 100.0 \cdot 0.0002557663690476190476190476190476190$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.025577$$
$$\therefore \ 100.0\ \text{oz (us)} = 0.025577 \ \text{bbl (dry) (us)}$$
Example 4
Convert $145.0\ \text{oz (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 145.0 \cdot 0.0002557663690476190476190476190476190$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.037086$$
$$\therefore \ 145.0\ \text{oz (us)} = 0.037086 \ \text{bbl (dry) (us)}$$
Example 5
Convert $200.0\ \text{oz (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 200.0 \cdot 0.0002557663690476190476190476190476190$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 0.051153$$
$$\therefore \ 200.0\ \text{oz (us)} = 0.051153 \ \text{bbl (dry) (us)}$$
