Fair enough, I use the non-breaking space for that.
Yep. But for longer expressions, we may need to consider the pros and
cons of preventing line breaks.
How about things like:
- 10 to 100 KM/H
- 7 to 8 years
and so on?
Personally I don't care much, except for headings and emphasized texts
where the appearance is important. For the latter,
"7&to&8 years" is probably sufficient - trying to prevent line
breaks where they would really disturb.
Or maybe this is a question for an English-usage newsgroup...
Well, similar questions arise for other languages, and notations like
"100 km/h" are really not English but belong to a special system of
notations, denotation of quantities, where the SI rules should be
applied. The document "Guide for the Use of the International System of
Units (SI)",
http://physics.nist.gov/Pubs/SP811/contents.html
can be useful reading, though it's somewhat anglocentric (e.g., in
strongly recommending the word "to" instead of a range dash) and
somewhat over-theoretical, especially when it frowns upon a notation
like "70 to 100 km/h", telling us to write "70 km/h to 100 km/h"
or "(70 to 100) km/h".
Anyway, a line break between a number and an SI unit is clearly
undesirable, because they belong tightly together (and people often
omit the space between them for this reason), so I would replace at
last the last space in "70 to 100 km/h" by a no-break space.
