Hi, the document "The International System of Units (SI) (9th ed)" states in chapter 5.4.3:
> The numerical value always precedes the unit and a space is always used to > separate the unit from the number. Thus the value of the quantity is the > product of the number and the unit. The space between the number and the unit > is regarded as a multiplication sign (just as a space between units implies > multiplication). The only exceptions to this rule are for the unit symbols > for degree, minute and second for plane angle, °, ′ and ″, respectively, for > which no space is left between the numerical value and the unit symbol. https://web.archive.org/web/20230113090424/https://www.bipm.org/documents/20126/41483022/SI-Brochure-9.pdf/ it would be nice if numfmt would support outputting formatted numbers that conform to this requirement. Currently, no space is placed between number and unit suffix. I tried to come up with a patch implementing this, which you can find attached. To preserve backwards compatibility, I introduced a new option called --space-separated. I made this option not specific to SI-conformance because it also works with custom suffixes and it has no special handling if the suffix happens to be a degree symbol. Please keep me CC-ed in replies, as I'm not subscribed to the list. Thank you for considering! cheers, josch
