How to convert Kilometer per hour to Foot per second
$$\text{Speed}_{\text{fts⁻¹}} = \text{Speed}_{\text{kmh⁻¹}} \cdot 0.9113444152814231554389034703995334$$
Examples
Example 1
Convert $30.0\ \text{kmh⁻¹}$ to $\text{fts⁻¹}$.
$$\text{Speed}_{\text{fts⁻¹}} = 30.0 \cdot 0.9113444152814231554389034703995334$$
$$\text{Speed}_{\text{fts⁻¹}} = 27.340332$$
$$\therefore \ 30.0\ \text{kmh⁻¹} = 27.340332 \ \text{fts⁻¹}$$
Example 2
Convert $70.0\ \text{kmh⁻¹}$ to $\text{fts⁻¹}$.
$$\text{Speed}_{\text{fts⁻¹}} = 70.0 \cdot 0.9113444152814231554389034703995334$$
$$\text{Speed}_{\text{fts⁻¹}} = 63.794109$$
$$\therefore \ 70.0\ \text{kmh⁻¹} = 63.794109 \ \text{fts⁻¹}$$
Example 3
Convert $120.0\ \text{kmh⁻¹}$ to $\text{fts⁻¹}$.
$$\text{Speed}_{\text{fts⁻¹}} = 120.0 \cdot 0.9113444152814231554389034703995334$$
$$\text{Speed}_{\text{fts⁻¹}} = 109.36133$$
$$\therefore \ 120.0\ \text{kmh⁻¹} = 109.36133 \ \text{fts⁻¹}$$
Example 4
Convert $130.0\ \text{kmh⁻¹}$ to $\text{fts⁻¹}$.
$$\text{Speed}_{\text{fts⁻¹}} = 130.0 \cdot 0.9113444152814231554389034703995334$$
$$\text{Speed}_{\text{fts⁻¹}} = 118.474774$$
$$\therefore \ 130.0\ \text{kmh⁻¹} = 118.474774 \ \text{fts⁻¹}$$
Example 5
Convert $165.0\ \text{kmh⁻¹}$ to $\text{fts⁻¹}$.
$$\text{Speed}_{\text{fts⁻¹}} = 165.0 \cdot 0.9113444152814231554389034703995334$$
$$\text{Speed}_{\text{fts⁻¹}} = 150.371829$$
$$\therefore \ 165.0\ \text{kmh⁻¹} = 150.371829 \ \text{fts⁻¹}$$
