Snowman44Are metric measurements like decameters and hectometers ever used?
Valdi, but rarely used, as it’s usually just as fast to say “two hundred meters” instead of “two hecto meters”.
However, those prefixes have other (non-SI) uses. A hectare is common way of referring to a 100x100 meter area. And a decare is 10 ares, i.e. 0.1 hectare.

Right, forgot about that one.
To be fair, once all the boomers are gone we’re probably going to go full kPa.
Meh, who knows. The change from millibars was quite a while ago.
