how do you convert km/h to m/s?

There are a thousand meters in one kilometer, so you can divide your number in km/h by 1,000 to get m/h. There are 3,600 seconds in an hour (60 x 60), so you then multiply by 3,600 to get m/s.

 

Simple way:

 

[math]\text{m/s} = \text{km/h} \times \frac{3600}{1000}[/math]

You don't really really need all that formula. To convert m/s to km/h just multiply with 3.6 and to convert km/s to m/s just divide with 3.6

You don't really really need all that formula. To convert m/s to km/h just multiply with 3.6 and to convert km/s to m/s just divide with 3.6

 

Which is exactly the same thing, just written differently!

OK, I know that and I know you know that too, but it's much simpler, that's why I posted it!

But conveys less information, if you know the method you can apply to other unit sets...

 

I'm just being annoying btw

Bad idea, it is very important that he understand unit conversion. He should then be able to convert any types of units, and to derive formulas like the one you posted for doing more than one conversion at once. Oh, and technically you are multiplying by 3.6 s/m km/h, and you don't replace any units later

 

And it should also be pointed out that unit conversion is a special case of multiplying by 1.

I would agree on this Mr Skeptic, but in this particular case unit conversion is actually pretty simple, basic physics stuff, so I guess the OP will have no problem on doing that.
