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.

    I’d say we use every 3 prefixes, nanometerw, micrometers, mm, m, km, than any much higher than that usually uses space units (parsecs, AU, lightyears, etc.)
