Fun fact: swimming records times are rounded to the hundreds of a second, because recording more precise times would require too high of a tolerance on the length of the pool at construction. I wonder if it's the same for some other sports!
Sounds like fertile ground for a Ph.D thesis that sparks a nail craze.
As below, this is why the metric system is superior. Centiseconds vs hectoseconds makes it much easier to see the mistake.
"I'd like 2 hecto ham" means 2 hectograms (200g, or 0.2kg)
It may sound strange if you are not used to it. I also have a feeling that the younger generations prefer just measuring in grams when it is less than a kg. Let's blame the school system ;-)
We also sometimes measure area as "dekar" (1000 sq m) and "hektar" (10000 sq m)
In English, "hexa" is the prefix for sixth from the Greek "hex".
