Question

How do I convert m/s to km or km/h?

is there a video that makes it easy to learn or can someone please explain

Answer 1

There are two ways of how you can do it.
See below.

Explanation:

1. The longer one
   For example, lets convert 1,36 `m/s` to `km/h`. Folow my steps from 1 to 3.
   
   Here is the video with an explanation, NOTE: start form 7:00
   

2. The shorter one
   If you want to convert 4,89 `km/h` to `m/s` you have to divide 4,89 with 3,6.
   `4.89/3.6`=1,36
   And if you want to convert 1,36 `m/s` to `km/h` you have to multiply 1,36 with 3,6.
   `1.36*3.6=4,89`
   

Answer 2

Look at this previous answer to a question on unit conversions:
https://socratic.org/questions/a-mile-is-5280-ft-long-1-ft-is-approximately-0-305-m-how-many-meters-are-there-i#469538

Explanation:

There would be no way to convert m/s to km. You would need to end up with units of `"distance/time"`. However conversion from m/s to km/h can be done and you already have 2 answers to help you do that. I decided to add my thoughts on unit conversion.

The KhanAcademy video one of your previous answers included is good. I decided to add my thoughts on unit conversion. You might get some additional help from the above link to an answer I wrote about 6 months ago to a Socratic question on this topic.

I hope these answers help you,
