Joules

Someone placed a comment that the joule should be marked as m·N, not N·m. Really? Just for reference, the official SI brochure marks it as N·m. What difference does it make? BW95 (talk) 18:40, 29 August 2009 (UTC)

Oh, I know that N·m makes it look like torque, but units-wise, does it matter? BW95 (talk) 19:04, 29 August 2009 (UTC)
The formula can be written either way really, I have seen it in textbooks as both - but it appears (at least as far as I can recall) as m·N more often. However I have never heard of why - It is probably just to keep things consistent. For example, Force is F=ma - I RARELY see it as F=am. —Preceding unsigned comment added by A.DeLarge23 (talkcontribs) 09:14, 24 May 2010 (UTC)
In BI units, a foot-pound is an energy, but a pound-foot is a torque. In metrics, a kilogram-metre is energy, but a metre-kilogram is a torque. You can only set newton-metres to joules, while a metre-newton is a joule per radian.Wendy.krieger (talk) 12:17, 4 August 2012 (UTC)

mN can be ambiguous (milli-Newtons vs meters-Newtons), but Nm can't. — Preceding unsigned comment added by 86.26.10.113 (talk) 00:51, 2 August 2015 (UTC)

metric prefixes

The joules section especially is in need of an overhaul to add prefixes in metric. It's a mess otherwise. — Preceding unsigned comment added by Cpt ricard (talkcontribs) 00:53, 13 August 2015 (UTC)
