$$\text{Volume}_{\text{bbl (beer)}} = \text{Volume}_{\text{tbsp (us)}} \cdot 0.0001260080646759105155392026705926814$$
Examples
Example 1
Convert $25.0\ \text{tbsp (us)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 25.0 \cdot 0.0001260080646759105155392026705926814$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.00315$$
$$\therefore \ 25.0\ \text{tbsp (us)} = 0.00315 \ \text{bbl (beer)}$$
Example 2
Convert $60.0\ \text{tbsp (us)}$ to $\text{bbl (beer)}$.

$$\text{Volume}_{\text{bbl (beer)}} = 140.0 \cdot 0.0001260080646759105155392026705926814$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.017641$$
$$\therefore \ 140.0\ \text{tbsp (us)} = 0.017641 \ \text{bbl (beer)}$$
Example 5
Convert $190.0\ \text{tbsp (us)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 190.0 \cdot 0.0001260080646759105155392026705926814$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.023942$$
$$\therefore \ 190.0\ \text{tbsp (us)} = 0.023942 \ \text{bbl (beer)}$$
