How to convert Liter to US oil barrel
$$\text{Volume}_{\text{bbl (oil)}} = \text{Volume}_{\text{l}} \cdot 0.006289810770432105128092855276408631$$
Examples
Example 1
Convert $50.0\ \text{l}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 50.0 \cdot 0.006289810770432105128092855276408631$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.314491$$
$$\therefore \ 50.0\ \text{l} = 0.314491 \ \text{bbl (oil)}$$
Example 2
Convert $85.0\ \text{l}$ to $\text{bbl (oil)}$.

$$\text{Volume}_{\text{bbl (oil)}} = 100.0 \cdot 0.006289810770432105128092855276408631$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.628981$$
$$\therefore \ 100.0\ \text{l} = 0.628981 \ \text{bbl (oil)}$$
Example 4
Convert $130.0\ \text{l}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 130.0 \cdot 0.006289810770432105128092855276408631$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.817675$$
$$\therefore \ 130.0\ \text{l} = 0.817675 \ \text{bbl (oil)}$$
Example 5
Convert $180.0\ \text{l}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 180.0 \cdot 0.006289810770432105128092855276408631$$
$$\text{Volume}_{\text{bbl (oil)}} = 1.132166$$
$$\therefore \ 180.0\ \text{l} = 1.132166 \ \text{bbl (oil)}$$
