To convert km/h to m/s, divide the speed by 3.6.
When converting kilometres per hour (km/h) to metres per second (m/s), you need to understand the relationship between these units. One kilometre is equal to 1,000 metres, and one hour is equal to 3,600 seconds. Therefore, to convert from km/h to m/s, you divide the number of kilometres by 1,000 to get metres, and then divide the number of hours by 3,600 to get seconds. Simplifying this, you end up dividing the speed in km/h by 3.6 to get the speed in m/s.
For example, if you have a speed of 72 km/h and you want to convert it to m/s, you would perform the following calculation:
\[ 72 \, \text{km/h} \div 3.6 = 20 \, \text{m/s} \]
This means that 72 km/h is equivalent to 20 m/s.
This conversion is useful in many real-world applications, such as understanding speed limits, calculating travel times, and analysing the speed of objects in physics problems. Remembering the factor of 3.6 makes it easy to switch between these units quickly and accurately.
