I’ve learned about them in school, but I’ve never heard anyone say something is 8 decameters long or anything like that. I’m an American.

Dekametre and hectometre, rarely. Mostly mm, cm, m, km.
In Europe, hg is relatively common, whereas in Canada, prices for deli products are “per 100 g” instead of per hg.
Also in Europe, cl and dl are common in recipes and bottles of alcohol, but in Canada, almost uniquely mL and L. (And yes, lowercase litre in Europe, but uppercase Litre in Canada, although that’s gradually changing.)
