Here we will show you how to convert 21 km/h to m/s. To avoid confusion, first note that 21 km/h to m/s is the same as 21 kilometers/hour to meters/second and 21 kilometer per hour to meter per second.
We will start by making a formula that you can use to convert any km/h to m/s, and then enter 21 km/h into our formula to get it converted to m/s.
There are 1000 meters (m) per kilometer and 3600 seconds (s) per hour. That means that one km/h is the same as 1000/3600 m/s. Furthermore, 1000/3600 can be simplified to 10/36. Therefore, to convert km/h to m/s, you multiply k/m by 10/36. Here is the km/h to m/s formula:
km/h × 10/36 = m/s
Now we can use our newly created formula to convert 21 km/h to m/s. Here is the answer, along with the math to convert 21 km/h to m/s.
km/h × 10/36 = m/s
21 × 10/36 = 35/6
21 km/h = 35/6 m/s
21 km/h ≈ 5.833 m/s
