How to convert Kilometer per hour to Speed of light in a vacuum
$$\text{Speed}_{\text{c}} = \text{Speed}_{\text{kmh⁻¹}} \cdot 9.265669311059779154877130957636625e - 10$$
Examples
Example 1
Convert $20.0\ \text{kmh⁻¹}$ to $\text{c}$.
$$\text{Speed}_{\text{c}} = 20.0 \cdot 9.265669311059779154877130957636625e - 10$$
$$\text{Speed}_{\text{c}} = 0.00000001853133862211955830975426191527325$$
$$\therefore \ 20.0\ \text{kmh⁻¹} = 0.00000001853133862211955830975426191527325 \ \text{c}$$
Example 2
Convert $75.0\ \text{kmh⁻¹}$ to $\text{c}$.
$$\text{Speed}_{\text{c}} = 75.0 \cdot 9.265669311059779154877130957636625e - 10$$
$$\text{Speed}_{\text{c}} = 0.00000006949251983294834366157848218227469$$
$$\therefore \ 75.0\ \text{kmh⁻¹} = 0.00000006949251983294834366157848218227469 \ \text{c}$$
Example 3
Convert $120.0\ \text{kmh⁻¹}$ to $\text{c}$.
$$\text{Speed}_{\text{c}} = 120.0 \cdot 9.265669311059779154877130957636625e - 10$$
$$\text{Speed}_{\text{c}} = 0.0000001111880317327173498585255714916395$$
$$\therefore \ 120.0\ \text{kmh⁻¹} = 0.0000001111880317327173498585255714916395 \ \text{c}$$
Example 4
Convert $150.0\ \text{kmh⁻¹}$ to $\text{c}$.
$$\text{Speed}_{\text{c}} = 150.0 \cdot 9.265669311059779154877130957636625e - 10$$
$$\text{Speed}_{\text{c}} = 0.0000001389850396658966873231569643645494$$
$$\therefore \ 150.0\ \text{kmh⁻¹} = 0.0000001389850396658966873231569643645494 \ \text{c}$$
Example 5
Convert $170.0\ \text{kmh⁻¹}$ to $\text{c}$.
$$\text{Speed}_{\text{c}} = 170.0 \cdot 9.265669311059779154877130957636625e - 10$$
$$\text{Speed}_{\text{c}} = 0.0000001575163782880162456329112262798226$$
$$\therefore \ 170.0\ \text{kmh⁻¹} = 0.0000001575163782880162456329112262798226 \ \text{c}$$
