A few days ago Marvin pointed out that our number formatting is non-standard.
Our style guide is based on Hack a Day’s and dictates units without spacing. According to the guide 10MHz is correct, 10 MHz is wrong. The SI standard is to use a space between the number and unit. We updated the style guide with SI standard (10 MHz is correct) and will follow it future tutorials, documentation, and blog posts.
Via the comments.
Excellent! I recently started being consistent about the space between numbers and units, so it is really convenient that Dangerous Prototypes is on the same page.
Don’t waste your time with this nonsense. The SI Fascists would have you speaking French if they had it their way. Any time someone invents something, the likes of the SI and ITU must come up with something almost identical but (intentionally) incompatible – to the detriment of all but themselves.
In the things that I have had published, I followed the SI guide, because the publishers required it.
In my own notes, doodles, and sketches for experiments and such, I always use the “no space” version, since that is what the accepted style was “back in the day”, when/where I learned it. It’s one of those things that I know is technically incorrect -but it’s a silly nitpick and just gets ignored.
It’s not like there’s any confusion about what is meant…
AFAIK to be 100% correct its not a full blank but a smaller fraction of a space which is equal to a multiplication character. This is the reason many LaTeX people use a “\,”-command if they have to write a number and a unit outside of the mathematics environment (and do not use a LaTeX package to deal with it). There will be no line-break too, which is also strongly suggested by the SI-style.
The LaTeX people have gathered a great detail of knowledge about this and its always a good idea to read how there packages work :)

@Drone: Woah why the bad feelings? Nobody is taking your freedom… just take it easy we are simply talking about numbers and units. Parsing text might be easier by following a certain rule and why not following what 99% of all print media are doing.
