How to convert US liquid gallon to Acre-foot
$$\text{Volume}_{\text{ac⋅ft}} = \text{Volume}_{\text{gal (liquid) (us)}} \cdot 0.000003068883277216610549943883277216611$$
Examples
Example 1
Convert $20.0\ \text{gal (liquid) (us)}$ to $\text{ac⋅ft}$.
$$\text{Volume}_{\text{ac⋅ft}} = 20.0 \cdot 0.000003068883277216610549943883277216611$$
$$\text{Volume}_{\text{ac⋅ft}} = 0.000061$$
$$\therefore \ 20.0\ \text{gal (liquid) (us)} = 0.000061 \ \text{ac⋅ft}$$
Example 2
Convert $75.0\ \text{gal (liquid) (us)}$ to $\text{ac⋅ft}$.
$$\text{Volume}_{\text{ac⋅ft}} = 75.0 \cdot 0.000003068883277216610549943883277216611$$
$$\text{Volume}_{\text{ac⋅ft}} = 0.00023$$
$$\therefore \ 75.0\ \text{gal (liquid) (us)} = 0.00023 \ \text{ac⋅ft}$$
Example 3
Convert $115.0\ \text{gal (liquid) (us)}$ to $\text{ac⋅ft}$.
$$\text{Volume}_{\text{ac⋅ft}} = 115.0 \cdot 0.000003068883277216610549943883277216611$$
$$\text{Volume}_{\text{ac⋅ft}} = 0.000353$$
$$\therefore \ 115.0\ \text{gal (liquid) (us)} = 0.000353 \ \text{ac⋅ft}$$
Example 4
Convert $150.0\ \text{gal (liquid) (us)}$ to $\text{ac⋅ft}$.
$$\text{Volume}_{\text{ac⋅ft}} = 150.0 \cdot 0.000003068883277216610549943883277216611$$
$$\text{Volume}_{\text{ac⋅ft}} = 0.00046$$
$$\therefore \ 150.0\ \text{gal (liquid) (us)} = 0.00046 \ \text{ac⋅ft}$$
Example 5
Convert $190.0\ \text{gal (liquid) (us)}$ to $\text{ac⋅ft}$.
$$\text{Volume}_{\text{ac⋅ft}} = 190.0 \cdot 0.000003068883277216610549943883277216611$$
$$\text{Volume}_{\text{ac⋅ft}} = 0.000583$$
$$\therefore \ 190.0\ \text{gal (liquid) (us)} = 0.000583 \ \text{ac⋅ft}$$
