How to convert Cubic inch to US barrel
$$\text{Volume}_{\text{bbl (US)}} = \text{Volume}_{\text{in³}} \cdot 0.0001374287088572802858517144231429946$$
Examples
Example 1
Convert $45.0\ \text{in³}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 45.0 \cdot 0.0001374287088572802858517144231429946$$
$$\text{Volume}_{\text{bbl (US)}} = 0.006184$$
$$\therefore \ 45.0\ \text{in³} = 0.006184 \ \text{bbl (US)}$$
Example 2
Convert $80.0\ \text{in³}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 80.0 \cdot 0.0001374287088572802858517144231429946$$
$$\text{Volume}_{\text{bbl (US)}} = 0.010994$$
$$\therefore \ 80.0\ \text{in³} = 0.010994 \ \text{bbl (US)}$$
Example 3
Convert $110.0\ \text{in³}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 110.0 \cdot 0.0001374287088572802858517144231429946$$
$$\text{Volume}_{\text{bbl (US)}} = 0.015117$$
$$\therefore \ 110.0\ \text{in³} = 0.015117 \ \text{bbl (US)}$$
Example 4
Convert $130.0\ \text{in³}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 130.0 \cdot 0.0001374287088572802858517144231429946$$
$$\text{Volume}_{\text{bbl (US)}} = 0.017866$$
$$\therefore \ 130.0\ \text{in³} = 0.017866 \ \text{bbl (US)}$$
Example 5
Convert $180.0\ \text{in³}$ to $\text{bbl (US)}$.
$$\text{Volume}_{\text{bbl (US)}} = 180.0 \cdot 0.0001374287088572802858517144231429946$$
$$\text{Volume}_{\text{bbl (US)}} = 0.024737$$
$$\therefore \ 180.0\ \text{in³} = 0.024737 \ \text{bbl (US)}$$
