How to convert Metric teaspoon to US beer barrel
$$\text{Volume}_{\text{bbl (beer)}} = \text{Volume}_{\text{tsp (metric)}} \cdot 0.00004260839554163684119030643896921976$$
Examples
Example 1
Convert $40.0\ \text{tsp (metric)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 40.0 \cdot 0.00004260839554163684119030643896921976$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.001704$$
$$\therefore \ 40.0\ \text{tsp (metric)} = 0.001704 \ \text{bbl (beer)}$$
Example 2
Convert $90.0\ \text{tsp (metric)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 90.0 \cdot 0.00004260839554163684119030643896921976$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.003835$$
$$\therefore \ 90.0\ \text{tsp (metric)} = 0.003835 \ \text{bbl (beer)}$$
Example 3
Convert $110.0\ \text{tsp (metric)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 110.0 \cdot 0.00004260839554163684119030643896921976$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.004687$$
$$\therefore \ 110.0\ \text{tsp (metric)} = 0.004687 \ \text{bbl (beer)}$$
Example 4
Convert $140.0\ \text{tsp (metric)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 140.0 \cdot 0.00004260839554163684119030643896921976$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.005965$$
$$\therefore \ 140.0\ \text{tsp (metric)} = 0.005965 \ \text{bbl (beer)}$$
Example 5
Convert $160.0\ \text{tsp (metric)}$ to $\text{bbl (beer)}$.
$$\text{Volume}_{\text{bbl (beer)}} = 160.0 \cdot 0.00004260839554163684119030643896921976$$
$$\text{Volume}_{\text{bbl (beer)}} = 0.006817$$
$$\therefore \ 160.0\ \text{tsp (metric)} = 0.006817 \ \text{bbl (beer)}$$
