How to convert US liquid gallon to US dry barrel
$$\text{Volume}_{\text{bbl (dry) (us)}} = \text{Volume}_{\text{gal (liquid) (us)}} \cdot 0.03273809523809523809523809523809524$$
Examples
Example 1
Convert $35.0\ \text{gal (liquid) (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 35.0 \cdot 0.03273809523809523809523809523809524$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 1.145833$$
$$\therefore \ 35.0\ \text{gal (liquid) (us)} = 1.145833 \ \text{bbl (dry) (us)}$$
Example 2
Convert $70.0\ \text{gal (liquid) (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 70.0 \cdot 0.03273809523809523809523809523809524$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 2.291667$$
$$\therefore \ 70.0\ \text{gal (liquid) (us)} = 2.291667 \ \text{bbl (dry) (us)}$$
Example 3
Convert $120.0\ \text{gal (liquid) (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 120.0 \cdot 0.03273809523809523809523809523809524$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 3.928571$$
$$\therefore \ 120.0\ \text{gal (liquid) (us)} = 3.928571 \ \text{bbl (dry) (us)}$$
Example 4
Convert $130.0\ \text{gal (liquid) (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 130.0 \cdot 0.03273809523809523809523809523809524$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 4.255952$$
$$\therefore \ 130.0\ \text{gal (liquid) (us)} = 4.255952 \ \text{bbl (dry) (us)}$$
Example 5
Convert $200.0\ \text{gal (liquid) (us)}$ to $\text{bbl (dry) (us)}$.
$$\text{Volume}_{\text{bbl (dry) (us)}} = 200.0 \cdot 0.03273809523809523809523809523809524$$
$$\text{Volume}_{\text{bbl (dry) (us)}} = 6.547619$$
$$\therefore \ 200.0\ \text{gal (liquid) (us)} = 6.547619 \ \text{bbl (dry) (us)}$$
