To convert from km/h to m/s, which mathematical operation should be performed after dividing by 3.6?

To convert a speed from kilometers per hour (km/h) to meters per second (m/s), you divide the speed in km/h by 3.6. The reason for this specific division is that 1 kilometer is equal to 1000 meters and 1 hour is equal to 3600 seconds. Therefore, when you want to convert kilometers per hour to meters per second, you are essentially converting both units to their respective base units.

Once you have divided by 3.6, no further mathematical operations such as multiplying, squaring, or adding 3.6 should be performed. The conversion is complete with the division alone, as it directly gives you the value in m/s. Hence, stating that none of the additional operations suggested (like multiplying by 3.6, squaring the result, or adding 3.6) are necessary after the division is accurate.
