Thanks for correction. I glossed right over that distinction. I don't believe there is any need in bike mechanics to measure in nanometers, joules, avogadro's number, any of that silly scientific stuff!

Yeah. I'm still suspicious when my caliper tells me a part is sized in non-whole millimeters.
Joules *are* useful. It's the amount of power over time! Watts/seconds! It's what biking's all about! (Not that I don't have to look that up every time it comes up...)
And Avogadro's Number describes the amount of snottiness my wife experiences when she goes in the bike shop downtown!
See? There's all sort of science things in bikes!

Huh! Look at that! We're all wrong! N·m or N m. Space or dot, lower-case "m". Google also has a lot of N-m. In any event, Nm is "nanometer".
Wikipedia, if I may paraphrase, says "Newton-meter something something joule something." So now I know better!

Power = Energy/Time

Wrong again! Energy/Time is Power (ie Joule/Sec = Watts).
Learn about it and then come at me with something better than a 'yo momma' joke.

I think I'll leave and let the 'scientists' finish this thread.
