How to convert Foot per second to Kilometer per hour
$$\text{Speed}_{\text{kmh⁻¹}} = \text{Speed}_{\text{fts⁻¹}} \cdot 1.09728$$
Examples
Example 1
Convert $20.0\ \text{fts⁻¹}$ to $\text{kmh⁻¹}$.
$$\text{Speed}_{\text{kmh⁻¹}} = 20.0 \cdot 1.09728$$
$$\text{Speed}_{\text{kmh⁻¹}} = 21.9456$$
$$\therefore \ 20.0\ \text{fts⁻¹} = 21.9456 \ \text{kmh⁻¹}$$
Example 2
Convert $75.0\ \text{fts⁻¹}$ to $\text{kmh⁻¹}$.
$$\text{Speed}_{\text{kmh⁻¹}} = 75.0 \cdot 1.09728$$
$$\text{Speed}_{\text{kmh⁻¹}} = 82.296$$
$$\therefore \ 75.0\ \text{fts⁻¹} = 82.296 \ \text{kmh⁻¹}$$
Example 3
Convert $120.0\ \text{fts⁻¹}$ to $\text{kmh⁻¹}$.
$$\text{Speed}_{\text{kmh⁻¹}} = 120.0 \cdot 1.09728$$
$$\text{Speed}_{\text{kmh⁻¹}} = 131.6736$$
$$\therefore \ 120.0\ \text{fts⁻¹} = 131.6736 \ \text{kmh⁻¹}$$
Example 4
Convert $135.0\ \text{fts⁻¹}$ to $\text{kmh⁻¹}$.
$$\text{Speed}_{\text{kmh⁻¹}} = 135.0 \cdot 1.09728$$
$$\text{Speed}_{\text{kmh⁻¹}} = 148.1328$$
$$\therefore \ 135.0\ \text{fts⁻¹} = 148.1328 \ \text{kmh⁻¹}$$
Example 5
Convert $185.0\ \text{fts⁻¹}$ to $\text{kmh⁻¹}$.
$$\text{Speed}_{\text{kmh⁻¹}} = 185.0 \cdot 1.09728$$
$$\text{Speed}_{\text{kmh⁻¹}} = 202.9968$$
$$\therefore \ 185.0\ \text{fts⁻¹} = 202.9968 \ \text{kmh⁻¹}$$
