Is it just me or does that tooltip differ somewhat from the marker?

Should say 69 KM/h (rather than kph)

Apology accepted. There is no such speed as a ‘knot per hour’ as a knot is already a speed*, so I don’t think there is any chance that people will read it as anything else other than kilometres per hour. It would be up to Tim D as to whether he wishes to change the description of the units in the tooltip to match those in Setup to kmph. 

kph uses less characters ;

Ive always thought it strange having two abbreviations for the same thing, I always thought kph was a more efficient and cleaner looking abbreviation at it only took the first letter of each word, assuming kilometre = one word.

Interestingly, we use double digits to differentiate other distance units e.g. mm for millimetre, nm for neutonmetre or nautical miles...

But here we are talking specifically about speed and so maybe it's ok to align to a different standard, miles per hour (mph), kilometres per hour (kph), knots per...oh wait!

And that's the trouble when there's a loose standard around the world. The amount of different units we use in aviation is bonkers. Europe tried to deal with it with the metric system but we must be 2-3 generations in and it's still not taken over (doesn't help when EASA switched millibars (metric?) to hectopascals).

Anyway, first world problems ;

Merry xmas

I also commented on this a year ago without success. kph is in my opinion not a common abbreviation for kilometers per hour and confused me many times and it seems more users are irritated.

It's shorter, and unambiguous. The fact two known people have been confused by it isn't enough reason to adopt a change with all the testing that would entail across the product to ensure the longer string didn't negatively affect textual output.
