Has the angstrom gone out of fashion as a unit? I saw the word today in an old physics book and realised I had otherwise seen it in years, maybe even decades.
Trix It's not an actual SI unit and I believe it's now specifically deprecated in some contexts. For the more precise end of the scale, I think picometers is the accepted SI unit. Or 0.1 nanometers, I suppose.
