I've never seen Mtr, sqm or gr. Even as a child, I knew the short of those unit names.
sqm instead of m^2 is also just a way of typing it on a mobile keyboard.

#12> 81 uL of catalyst -> 81 μL of catalyst Oh, interesting. NIST recommends "L": https://www.nist.gov/pml/special-publication-811/nist-guide-...
That line refers to the 'u' substituting for 'μ', the greek letter mu, not the L symbol. https://www.nayuki.io/page/common-mistakes-when-using-the-me...

#13Earlier quoted context omitted.
Same for "2.4 GHz wireless network" but it's supposed to be 2.4 gigahertz if fully spelled. I suppose there is a logic behind but it's not obvious.
60 watts , later 20 kW. I don't know, but it seems to me that if they wanted to be scientific they wouldn't be seemingly arbitrary in the capitalization rules
I had structural engineering and electronics in school and especially when you get compound units like Nm (newton meters) not wondering if the N is a newton or the SI-prefix nano is not nothing.
In the end the reason for the weird capitalization is just to avoid situations where that ambiguity will occur.
Re: Common mistakes when using the metric system
#14I was surprised to see "L" as the "only correct" (though as minor mistake) abbreviation for a liter, being certain "l" or "ℓ" is the way to go, as that's how I was taught so far. Turns out that SI actually allows both "l" and "L", but I would only ever use the uppercase if it's a sans-serif font in a non-prefixed unit ("L" as opposed to "ml"). I've never seen any can or bottle using "mL" or "cL".
Some of the examples go pretty far too, either calling spelling I'd never see a "common mistake" (like "gr." for grams), or by being too scientifically correct for a casual usage, for example in a press article ("(100 + 200) grams", right).
But then I saw "Set the oven to 450 K", and I realized that the examples are to be taken with a grain of salt :)

#16Doesn't seem right. I wonder why they claim cc and Å are 'deprecated'.
cc maybe in favor of unicode's ㎤

Note: The official SI unit “liter” was written “l” until a couple of decades ago, when they changed it to “L” due to frequent legibility issues (l/I/1). Some old texts use the old convention.

I have seen usage of kvm (kvadratmeter) in Sweden

Almost all cooking books I have do this (sample size is not big though, and with almost all I mean all except one). I don't know why though, maybe it's an old abbreviation which stuck in certain text types?
