These dogs can reach a height of 100 cm.
These dogs can grow up to a height of 100 cms.


Which of the above two sound better and make more sense? Thanks.

The first is fine; the second needs rephrasing as "These dogs grow to a....".

They both make perfect sense.

Thanks, Anglika.

But I still have a question--should I use 100 cm or cms and why?
