Examples
Example 1
Convert $50.0\ \text{tsp (metric)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 50.0 \cdot 0.02113376418865187323039199372873300$$
$$\text{Volume}_{\text{cup (us)}} = 1.056688$$

Example 4
Convert $135.0\ \text{tsp (metric)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 135.0 \cdot 0.02113376418865187323039199372873300$$
$$\text{Volume}_{\text{cup (us)}} = 2.853058$$
$$\therefore \ 135.0\ \text{tsp (metric)} = 2.853058 \ \text{cup (us)}$$
Example 5
Convert $185.0\ \text{tsp (metric)}$ to $\text{cup (us)}$.
$$\text{Volume}_{\text{cup (us)}} = 185.0 \cdot 0.02113376418865187323039199372873300$$
$$\text{Volume}_{\text{cup (us)}} = 3.909746$$
$$\therefore \ 185.0\ \text{tsp (metric)} = 3.909746 \ \text{cup (us)}$$
