How to convert UK pint to US beer barrel
$$\text{Volume}_{\text{bbl (beer)}} = \text{Volume}_{\text{pt (uk)}} \cdot 0.004842540022196995684171004978339506$$
Examples
Example 1
Convert $20.0\ \text{pt (uk)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 20.0 \cdot 0.004842540022196995684171004978339506$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.096851$$
$$\therefore \ 20.0\ \text{pt (uk)} = 0.096851 \ \text{bbl (beer)}$$
Example 2
Convert $65.0\ \text{pt (uk)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 65.0 \cdot 0.004842540022196995684171004978339506$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.314765$$
$$\therefore \ 65.0\ \text{pt (uk)} = 0.314765 \ \text{bbl (beer)}$$
Example 3
Convert $100.0\ \text{pt (uk)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 100.0 \cdot 0.004842540022196995684171004978339506$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.484254$$
$$\therefore \ 100.0\ \text{pt (uk)} = 0.484254 \ \text{bbl (beer)}$$
Example 4
Convert $130.0\ \text{pt (uk)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 130.0 \cdot 0.004842540022196995684171004978339506$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.62953$$
$$\therefore \ 130.0\ \text{pt (uk)} = 0.62953 \ \text{bbl (beer)}$$
Example 5
Convert $180.0\ \text{pt (uk)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 180.0 \cdot 0.004842540022196995684171004978339506$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.871657$$
$$\therefore \ 180.0\ \text{pt (uk)} = 0.871657 \ \text{bbl (beer)}$$
