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.

    For distance, no. Day to day we use mm, cm, m and km. But in more specialised settings (e.g. construction) I’ve seen sometimes decameters.

    For weight yes, grams, hectograms, kg, tons. Liquids is usually ml, cl, liters, hectoliters (not sure it’s spelt that way).

    In labs I’ve also seen also micro and nano of all three units.

      Use cubes for water. Short for cubic meter. That is 1 meter by 1 meter by 1 meter which is also exactly 1000 liters.

      This is one of the convenient metric parameters where they made an easy conversion allowing you to precisely use distance to calculate volume.
