Why so little love for the nanofarad?

I have pf, nF and uf for every capacitor value in my inventory spreadsheet. Saves me from having to think/convert on the fly when ordering and suppliers are not consistentYep. I know that a 104 is 100nF, but I check the chart every time just to be sure.

Yeah, that refers to the voltage and the tolerance -- that's a whole other chart...

I don't actually know if they sell those charts. Whenever I've ordered something from them, they just throw one in the package. There's a great resistor color-code chart on the other side.

Tell me about it! When I worked in datacomm I needed to know a lot of them.. and also the companies and products that didn’t follow them or very loosely followed them. And let me tell you, the list of companies that actually followed the standards was smaller than those that didn’t !

No kidding. Mouser lists this Kemet film cap as 8200pF, both in the search engine and the primary description. But a little lower down:
And of course on the cap itself it says 8n2.

As someone who has installed a 100r resistor where a 100k was supposed to go, I'll be the first to tell you that sometimes you do (or at least I do) need a chart.

Having 3 or 4 different ways to refer to the same part is how errors creep in and airplane door plugs fly out. I don't know about you, but sometimes I don't fire on all cylinders. I may be tired, bored, distracted, zoned out, buzzed... At such times the last thing I need is coming up with the extra mental bandwidth to compute that 0.0012uF is 1.2nF and not 12nF.

It’s part of my troubleshooting flow.

That'd be .1J63. 1J63 would be 1uF. J is +/-5% tolerance.

They're fairly well hammered in now, but the way I learned is to just simply remember 104 is 100nF, and derive from there.
104 = 100nF, 103 = 10nF, 101 = 1nF, etc.
I don't even bother trying to memorize the EIA-96 SMD resistor codes...

Not to seem argumentative, but you seem to be arguing the case for not using nano as a third way to reference.

On Gboard/Android under the π symbol. Hold and it'll open.
Umlauts üëïöä should be by default of you hold the respective keys. Other things you need to enable localized languages for the keyboard.

I created a note on my phone that has several special characters so I can just copy-n-paste . . . .
Ω ℧ • β µF °F £ ± ∞ ÷ ¢ ö π ∞ ¢ — ⁂ ∴ ⸮ ‽ ≠ ꓘ © 𝕏 ⧚ ⫪ ⋹
And I figured, while I'm at it, add some favorite emoticons tho don't shift . . . . (no idea how these will translate/appear on other platforms)
