How to convert US teaspoon to US liquid gallon
$$\text{Volume}_{\text{gal (liquid) (us)}} = \text{Volume}_{\text{tsp (us)}} \cdot 0.001302083334984408660571760929457708$$
Examples
Example 1
Convert $30.0\ \text{tsp (us)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 30.0 \cdot 0.001302083334984408660571760929457708$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 0.039063$$
$$\therefore \ 30.0\ \text{tsp (us)} = 0.039063 \ \text{gal (liquid) (us)}$$
Example 2
Convert $80.0\ \text{tsp (us)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 80.0 \cdot 0.001302083334984408660571760929457708$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 0.104167$$
$$\therefore \ 80.0\ \text{tsp (us)} = 0.104167 \ \text{gal (liquid) (us)}$$
Example 3
Convert $110.0\ \text{tsp (us)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 110.0 \cdot 0.001302083334984408660571760929457708$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 0.143229$$
$$\therefore \ 110.0\ \text{tsp (us)} = 0.143229 \ \text{gal (liquid) (us)}$$
Example 4
Convert $145.0\ \text{tsp (us)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 145.0 \cdot 0.001302083334984408660571760929457708$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 0.188802$$
$$\therefore \ 145.0\ \text{tsp (us)} = 0.188802 \ \text{gal (liquid) (us)}$$
Example 5
Convert $170.0\ \text{tsp (us)}$ to $\text{gal (liquid) (us)}$.
$$\text{Volume}_{\text{gal (liquid) (us)}} = 170.0 \cdot 0.001302083334984408660571760929457708$$
$$\text{Volume}_{\text{gal (liquid) (us)}} = 0.221354$$
$$\therefore \ 170.0\ \text{tsp (us)} = 0.221354 \ \text{gal (liquid) (us)}$$
