The SI system is a metric system and also defines the use of the words describing powers of ten. The use of kiloseconds also isn’t wrong, it just means 1000 seconds, obviously. But it only makes sense in context (for example short lived isotopes).
The same way “Megameter” is formally correct but no one uses it because there is rarely a context where this was useful.
