Just curious, which unit do you personally use for torque, Newton meters or Joules, or as a third option ft*lbs.

The actual units are the same, but in my opinion, Joules should be used only for measurements related to Energy.

N*M or lb*ft. joules, while having the same unit dimensions, mean something entirely different. torque is an angular force, as T = moment of inertia*angular acceleration

That was pretty random. Relative of yours?;)

N*m or ft*lb, just because that helps keep in your mind the fact that you're measuring torque.

All the kiddies who want to act "euro" prefer N.m

All the real gearheads will prefer ft*lbs if they're from the US.

Just about all US documentation refers to torque in ft*lbs.

I work in a science lab. I'm trying to act "scientific", not euro.:roll:

But when I work on my car, yeah, it's ft-lbs.

Also English in the machine shop, though I wish that was different.

The worst is when I have to machine something for the lab :(
