I'm not sure how to write the following: a 2 metre high tree, a 2-metre high tree or a 2-metre-high tree?
Thanks for helping!
I'd suggest that you can omit the word "high."
A two-metre tree.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
Very interesting topic..
But what if I have to write it in a research paper by using measurement units? Would this rule still remain valid?
The journals I write for do not have specific guidelines for this issue, so I think that I should stick with traditional grammar rules....
That said... should I write
a 40-m-long road?
'A 40metre-long road.'
40m might be taken to mean '40 miles'.
thanks. What I meant was: does the rule also stands when measurement units are used?
i.e.: is it ok to write
- a 2-cm-long stick
- a 45-°C-temperature
and so on... all hyphened?
