How to convert Milliliter to US beer barrel
$$\text{Volume}_{\text{bbl (beer)}} = \text{Volume}_{\text{ml}} \cdot 0.000008521679108327368238061287793843952$$
Examples
Example 1
Convert $35.0\ \text{ml}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 35.0 \cdot 0.000008521679108327368238061287793843952$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.000298$$
$$\therefore \ 35.0\ \text{ml} = 0.000298 \ \text{bbl (beer)}$$
Example 2
Convert $70.0\ \text{ml}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 70.0 \cdot 0.000008521679108327368238061287793843952$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.000597$$
$$\therefore \ 70.0\ \text{ml} = 0.000597 \ \text{bbl (beer)}$$
Example 3

$$\text{Volume}_{\text{bbl (beer)}} = 115.0 \cdot 0.000008521679108327368238061287793843952$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.00098$$
$$\therefore \ 115.0\ \text{ml} = 0.00098 \ \text{bbl (beer)}$$
Example 4
Convert $135.0\ \text{ml}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 135.0 \cdot 0.000008521679108327368238061287793843952$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.00115$$
$$\therefore \ 135.0\ \text{ml} = 0.00115 \ \text{bbl (beer)}$$
Example 5
Convert $185.0\ \text{ml}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 185.0 \cdot 0.000008521679108327368238061287793843952$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.001577$$
$$\therefore \ 185.0\ \text{ml} = 0.001577 \ \text{bbl (beer)}$$
