$$\text{Volume}_{\text{liq.gi}} = \text{Volume}_{\text{tsp (us)}} \cdot 0.04166666671950107713829634974264665$$
Examples
Example 1
Convert $20.0\ \text{tsp (us)}$ to $\text{liq.gi}$.
$$\text{Volume}_{\text{liq.gi}} = 20.0 \cdot 0.04166666671950107713829634974264665$$
$$\text{Volume}_{\text{liq.gi}} = 0.833333$$
$$\therefore \ 20.0\ \text{tsp (us)} = 0.833333 \ \text{liq.gi}$$
Example 2
Convert $90.0\ \text{tsp (us)}$ to $\text{liq.gi}$.
$$\text{Volume}_{\text{liq.gi}} = 90.0 \cdot 0.04166666671950107713829634974264665$$
$$\text{Volume}_{\text{liq.gi}} = 3.75$$
$$\therefore \ 90.0\ \text{tsp (us)} = 3.75 \ \text{liq.gi}$$
Example 3
Convert $100.0\ \text{tsp (us)}$ to $\text{liq.gi}$.
$$\text{Volume}_{\text{liq.gi}} = 100.0 \cdot 0.04166666671950107713829634974264665$$
$$\text{Volume}_{\text{liq.gi}} = 4.166667$$
$$\therefore \ 100.0\ \text{tsp (us)} = 4.166667 \ \text{liq.gi}$$
Example 4
Convert $140.0\ \text{tsp (us)}$ to $\text{liq.gi}$.
$$\text{Volume}_{\text{liq.gi}} = 140.0 \cdot 0.04166666671950107713829634974264665$$
$$\text{Volume}_{\text{liq.gi}} = 5.833333$$
$$\therefore \ 140.0\ \text{tsp (us)} = 5.833333 \ \text{liq.gi}$$
Example 5
Convert $185.0\ \text{tsp (us)}$ to $\text{liq.gi}$.
$$\text{Volume}_{\text{liq.gi}} = 185.0 \cdot 0.04166666671950107713829634974264665$$
$$\text{Volume}_{\text{liq.gi}} = 7.708333$$
$$\therefore \ 185.0\ \text{tsp (us)} = 7.708333 \ \text{liq.gi}$$
