What is the correct conversion factor when changing meters per second to kilometers per hour?

When converting meters per second (m/s) to kilometers per hour (km/h), understanding the relationship between these units is crucial.

One meter per second is equivalent to 1,000 meters in a kilometer and there are 3,600 seconds in an hour. To convert m/s to km/h, you can use the following conversion:

1 m/s = (1 m/s) × (3600 s/1 h) × (1 km/1000 m)

This simplifies as follows:

1 m/s = (3600 / 1000) km/h = 3.6 km/h

Thus, if you want to convert a speed measured in meters per second to kilometers per hour, you multiply the speed in m/s by 3.6. This is why the conversion factor is to multiply by 3.6 when changing meters per second to kilometers per hour.
