>We have centimeter (10 mm) then decimeter (100mm)
Does anyone actually use those? I think I would throw up a little in my mouth if I saw either of those on a mechanical drawing.

Likewise, there is also deca- and hecto-. Hectograms are used for shopping.
Decameter (dam, 10 m) is never used, but there is a non-SI unit of area based on it, called the are. Nobody uses the are, but its multiple the hectare (1 square hectometer) is common in some countries when talking about land plots. It's a little less than 2.5 acres, for people in the US.
