Wait, people actually use cL in Germany? I thought most metric countries would say "400 mL" instead (that's what we do in Canada anyway). It seems so arbitrary to me - if not sticking to powers of 3, then why not just say 4 dL?

(Not that there's anything "wrong" about this - I just don't understand why.)

well, normally people use ml for everything, but cups and bottles from US companies are sold in cl sizes. Coke glass: 50cl. IKEA glass: 200ml. McDonalds cup: 40cl. Glass in a local restaurant (if not coke glass): 200ml.
