Is the units of speed an ordered set?

Hi

There was a question where the asker wanted to know which of km/h and m/s is greater.
If I'm right,this question makes sense only if the units of speed create an ordered set.

Math Focus: Mainly analysis and algebra
Units are not values. That is not to say that you can't order them, but we don't usually.

However, a speed $v$ in km/h is equal to $\frac{1000}{3600}v$ m/s because there are 1000m in a km and 3600s in an hour.

So representing the speed in km/h gives a smaller number than representing it in m/s.
