How to convert UK gill to US oil barrel
$$\text{Volume}_{\text{bbl (oil)}} = \text{Volume}_{\text{gi}} \cdot 0.0008935639326673027750553640138602661$$
Examples
Example 1
Convert $25.0\ \text{gi}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 25.0 \cdot 0.0008935639326673027750553640138602661$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.022339$$
$$\therefore \ 25.0\ \text{gi} = 0.022339 \ \text{bbl (oil)}$$
Example 2
Convert $60.0\ \text{gi}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 60.0 \cdot 0.0008935639326673027750553640138602661$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.053614$$
$$\therefore \ 60.0\ \text{gi} = 0.053614 \ \text{bbl (oil)}$$
Example 3
Convert $120.0\ \text{gi}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 120.0 \cdot 0.0008935639326673027750553640138602661$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.107228$$
$$\therefore \ 120.0\ \text{gi} = 0.107228 \ \text{bbl (oil)}$$
Example 4
Convert $140.0\ \text{gi}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 140.0 \cdot 0.0008935639326673027750553640138602661$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.125099$$
$$\therefore \ 140.0\ \text{gi} = 0.125099 \ \text{bbl (oil)}$$
Example 5
Convert $190.0\ \text{gi}$ to $\text{bbl (oil)}$.
$$\text{Volume}_{\text{bbl (oil)}} = 190.0 \cdot 0.0008935639326673027750553640138602661$$
$$\text{Volume}_{\text{bbl (oil)}} = 0.169777$$
$$\therefore \ 190.0\ \text{gi} = 0.169777 \ \text{bbl (oil)}$$
