There are \(64.8\) kilometers per hour in \(18\) meters per second.

There are \(3.6\) kilometers per hour in a meter per second.

The conversion factor from meters per second to kilometers per hour is \(3.6\frac{\text{kilometers per hour}}{\text{meters per second}}\).

Multiply the quantity in meters per second by the conversion factor to get the quantity in kilometers per hour: \[18 \text{ meters per second} \times 3.6\tfrac{\text{kilometers per hour}}{\text{meters per second}} = 64.8 \text{ kilometers per hour}\]
