Talk:Newton metre
From Wikipedia, the free encyclopedia
[edit] newtre
Would anyone care to provide some evidence to back up the claim that "Some people, as a matter of convenience, have opted to use a gramatical contraction of these units that is outside of the traditional SI vernacular. Instead of saying newton-metre, these people will, in casual conversation, refer to torque in units of the "newtre"."?
If there is no significant use of this sort, I will delete it. Gene Nygaard 03:21, 21 Feb 2005 (UTC)
- Never heard of it, and Google evidently hasn't either — Egil 07:31, 21 Feb 2005 (UTC)
[edit] Newton metre or newton-metre?
The latter looks right to me. Which is it? —Michael Z. 2005-10-13 18:29 Z
- Either. I like the hyphenated version better, too, that is to say newton-meter rather than newton meter, both of which are also correct. Gene Nygaard 20:14, 13 October 2005 (UTC)

- The official SI website uses the form newton metre. See: http://www.bipm.org/en/si/si_brochure/chapter2/2-2/2-2-2.html

- The US NIST prefers a space character rather than a hyphen. It says that is also the preference of American National Standard for Metric Practice ANSI/IEEE Std 268-1992. See: http://physics.nist.gov/Pubs/SP811/sec09.html Bobblewik 23:03, 13 October 2005 (UTC)
[edit] newton metre vs. joule
While the article is correct (as far as I know, anyway), I feel the "joule" paragraph is confusing and makes it almost seem as if there is some relationship between a newton metre and a joule, other than the dimension. Specifically, the sentence about the "normal" vs. "colinear" arm sounds like maybe a newton metre is a joule except measured in a different direction.
It seems to me that the article should just state something like "although a joule can also be (or maybe "is often"?) expressed in units of newton metres, it is an unrelated unit of measure". Kwh033 04:12, 11 November 2006 (UTC)
