*screeches in metric*

So y’all know I love the SI units, right? Hell, the “kilogram” tag on this blog is used frequently enough that it shows up in the “Tags” list on my front page.

Well, another closely-related thing I love are the SI prefixes. These are things like kilo or nano or yocto (which got its own blog a while back) that precede a unit and indicate either a multiple (like “kilo” suggests a thousand times something) or a fraction (like “milli” suggests a millionth of something) of the unit. Kilogram, nanosecond, millimeter, etc.

That kinda stuff.

Well, I guess four new prefixes have been proposed for the next levels of super big and super small: ronna and ronto for 1027 and 10-27 respectively, and quecca and quento for 1030 and 10-30, respectively. If they’re approved, they’re set to be officially put into place in 2022, making them the first prefixes approved since 1991.

And that is way too cool.

(I love the prefixes and I’m not sorry.)
