How to convert Foot per second to Mile per hour
$$\text{Speed}_{\text{mph}} = \text{Speed}_{\text{fts⁻¹}} \cdot 0.6818181818181818181818181818181818$$
Examples
Example 1
Convert $35.0\ \text{fts⁻¹}$ to $\text{mph}$.
$$\text{Speed}_{\text{mph}} = 35.0 \cdot 0.6818181818181818181818181818181818$$
$$\text{Speed}_{\text{mph}} = 23.863636$$
$$\therefore \ 35.0\ \text{fts⁻¹} = 23.863636 \ \text{mph}$$
Example 2
Convert $90.0\ \text{fts⁻¹}$ to $\text{mph}$.
$$\text{Speed}_{\text{mph}} = 90.0 \cdot 0.6818181818181818181818181818181818$$
$$\text{Speed}_{\text{mph}} = 61.363636$$
$$\therefore \ 90.0\ \text{fts⁻¹} = 61.363636 \ \text{mph}$$
Example 3
Convert $115.0\ \text{fts⁻¹}$ to $\text{mph}$.
$$\text{Speed}_{\text{mph}} = 115.0 \cdot 0.6818181818181818181818181818181818$$
$$\text{Speed}_{\text{mph}} = 78.409091$$
$$\therefore \ 115.0\ \text{fts⁻¹} = 78.409091 \ \text{mph}$$
Example 4
Convert $150.0\ \text{fts⁻¹}$ to $\text{mph}$.
$$\text{Speed}_{\text{mph}} = 150.0 \cdot 0.6818181818181818181818181818181818$$
$$\text{Speed}_{\text{mph}} = 102.272727$$
$$\therefore \ 150.0\ \text{fts⁻¹} = 102.272727 \ \text{mph}$$
Example 5
Convert $165.0\ \text{fts⁻¹}$ to $\text{mph}$.
$$\text{Speed}_{\text{mph}} = 165.0 \cdot 0.6818181818181818181818181818181818$$
$$\text{Speed}_{\text{mph}} = 112.5$$
$$\therefore \ 165.0\ \text{fts⁻¹} = 112.5 \ \text{mph}$$
