How to convert Stone to Ton (US)
$$\text{Mass}_{\text{ton (us)}} = \text{Mass}_{\text{st}} \cdot 0.007$$
Examples
Example 1
Convert $30.0\ \text{st}$ to $\text{ton (us)}$.
$$\text{Mass}_{\text{ton (us)}} = 30.0 \cdot 0.007$$
$$\text{Mass}_{\text{ton (us)}} = 0.21$$
$$\therefore \ 30.0\ \text{st} = 0.21 \ \text{ton (us)}$$
Example 2
Convert $90.0\ \text{st}$ to $\text{ton (us)}$.
$$\text{Mass}_{\text{ton (us)}} = 90.0 \cdot 0.007$$
$$\text{Mass}_{\text{ton (us)}} = 0.63$$
$$\therefore \ 90.0\ \text{st} = 0.63 \ \text{ton (us)}$$
Example 3
Convert $120.0\ \text{st}$ to $\text{ton (us)}$.
$$\text{Mass}_{\text{ton (us)}} = 120.0 \cdot 0.007$$
$$\text{Mass}_{\text{ton (us)}} = 0.84$$
$$\therefore \ 120.0\ \text{st} = 0.84 \ \text{ton (us)}$$
Example 4
Convert $135.0\ \text{st}$ to $\text{ton (us)}$.
$$\text{Mass}_{\text{ton (us)}} = 135.0 \cdot 0.007$$
$$\text{Mass}_{\text{ton (us)}} = 0.945$$
$$\therefore \ 135.0\ \text{st} = 0.945 \ \text{ton (us)}$$
Example 5
Convert $185.0\ \text{st}$ to $\text{ton (us)}$.
$$\text{Mass}_{\text{ton (us)}} = 185.0 \cdot 0.007$$
$$\text{Mass}_{\text{ton (us)}} = 1.295$$
$$\therefore \ 185.0\ \text{st} = 1.295 \ \text{ton (us)}$$
