Sure, and the speed of vehicles is measured in kph (and probably frequencies in cps, or in this space more likely kilomegacycles). I didn’t complain about anything. I just noted the very low technical competence signaled by this usage in the press release (what pushed me over the edge was of course the “terra”). Competence signaling is often inadvertent, and it can be very useful for the recipient of a message. To keep with the side-track you opened: I wouldn't complain about Tbps, because I know it’s the vernacular, and maybe I shouldn’t have mentioned the correct scientific notation, because even much of the science in this space is written up in vernacular. I work with networks that offer a sustained data rate of 2-200 mbit/s (yes, millibit per seconds), so I really can’t find a lot of value in using the wrong case for the prefixes. You don’t easily find a press release with “tbps” (well, maybe with tbsp, table spoons). If it rocks your boat, nobody will stop you from writing that way, and the trade press in UK/AU really seems to like that (did I say anything about competence signaling yet?). I know most people here don’t care (because they don’t have to(*), literally), but there are standards for these things, and there are reasons for the way that they have turned out to be. If you want to taste a little treatise from engineers who do care (because their job is building things that measure), you can look up https://u.nu/correct-units . Can we now return to spam-bashing? Grüße, Carsten (*) I apologize for this little pun. Or, maybe we are the phone company now?
