How to convert UK quart to US oil barrel
$$\text{Volume}_{\text{bbl (oil)}} = \text{Volume}_{\text{qt (uk)}} \cdot 0.007148511461338422200442912110882128$$
Examples
Example 1
Convert $20.0\ \text{qt (uk)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 20.0 \cdot 0.007148511461338422200442912110882128$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.14297$$
$$\therefore \ 20.0\ \text{qt (uk)} = 0.14297 \ \text{bbl (oil)}$$
Example 2
Convert $75.0\ \text{qt (uk)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 75.0 \cdot 0.007148511461338422200442912110882128$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.536138$$
$$\therefore \ 75.0\ \text{qt (uk)} = 0.536138 \ \text{bbl (oil)}$$
Example 3
Convert $110.0\ \text{qt (uk)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 110.0 \cdot 0.007148511461338422200442912110882128$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.786336$$
$$\therefore \ 110.0\ \text{qt (uk)} = 0.786336 \ \text{bbl (oil)}$$
Example 4
Convert $150.0\ \text{qt (uk)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 150.0 \cdot 0.007148511461338422200442912110882128$$
$$\text{Volume}_{\text{bbl (oil)}} = 1.072277$$
$$\therefore \ 150.0\ \text{qt (uk)} = 1.072277 \ \text{bbl (oil)}$$
Example 5
Convert $160.0\ \text{qt (uk)}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 160.0 \cdot 0.007148511461338422200442912110882128$$
$$\text{Volume}_{\text{bbl (oil)}} = 1.143762$$
$$\therefore \ 160.0\ \text{qt (uk)} = 1.143762 \ \text{bbl (oil)}$$
