How to convert US teaspoon to UK pint
$$\text{Volume}_{\text{pt (uk)}} = \text{Volume}_{\text{tsp (us)}} \cdot 0.008673689434217096449916301701022197$$
Examples
Example 1
Convert $40.0\ \text{tsp (us)}$ to $\text{pt (uk)}$.
$$\text{Volume}_{\text{pt (uk)}} = 40.0 \cdot 0.008673689434217096449916301701022197$$
$$\text{Volume}_{\text{pt (uk)}} = 0.346948$$
$$\therefore \ 40.0\ \text{tsp (us)} = 0.346948 \ \text{pt (uk)}$$
Example 2
Convert $65.0\ \text{tsp (us)}$ to $\text{pt (uk)}$.
$$\text{Volume}_{\text{pt (uk)}} = 65.0 \cdot 0.008673689434217096449916301701022197$$
$$\text{Volume}_{\text{pt (uk)}} = 0.56379$$
$$\therefore \ 65.0\ \text{tsp (us)} = 0.56379 \ \text{pt (uk)}$$
Example 3
Convert $115.0\ \text{tsp (us)}$ to $\text{pt (uk)}$.
$$\text{Volume}_{\text{pt (uk)}} = 115.0 \cdot 0.008673689434217096449916301701022197$$
$$\text{Volume}_{\text{pt (uk)}} = 0.997474$$
$$\therefore \ 115.0\ \text{tsp (us)} = 0.997474 \ \text{pt (uk)}$$
Example 4
Convert $135.0\ \text{tsp (us)}$ to $\text{pt (uk)}$.
$$\text{Volume}_{\text{pt (uk)}} = 135.0 \cdot 0.008673689434217096449916301701022197$$
$$\text{Volume}_{\text{pt (uk)}} = 1.170948$$
$$\therefore \ 135.0\ \text{tsp (us)} = 1.170948 \ \text{pt (uk)}$$
Example 5
Convert $185.0\ \text{tsp (us)}$ to $\text{pt (uk)}$.
$$\text{Volume}_{\text{pt (uk)}} = 185.0 \cdot 0.008673689434217096449916301701022197$$
$$\text{Volume}_{\text{pt (uk)}} = 1.604633$$
$$\therefore \ 185.0\ \text{tsp (us)} = 1.604633 \ \text{pt (uk)}$$
