Yes, having a sentence ...

The change in the value of the residual, after 2 hours or 35 iterations, should not exceed 23 ppm is a requirement of various standards, among which are NIST 543:62 and FIPS
180 published in 2017.

... is slightly confusing wih the line breaks as above.


I had to go back and examine that sentence to see where the "problem" was. I read through that at speed without any issue, no hesitation, full comprehension, in one pass.

The separation of "23" and "ppm" is for readability. One's mind picks up "twenty-three" and "ppm" automatically.

If displayed as "23ppm", one's mind has to parse/extract "twenty-three" and "ppm", hence lower readability.

At least in English, every guideline, technical standard or proposal submission standard I can recall seeing that addressed quantities and unit abbreviations, stated to leave a space between the quantity and the unit abbreviation. A quick search online didn't find any that were different from that.

I believe it goes beyond readability and into an issue of perceived credibility. 'If they didn't get the writing correct', or inconsistent, what are they like on other details...

my two cents,

Michael
