As for what units to use... If you live in the states, get used to working in both because it is going to be a missmash for the foreseeable future. 
Thinking about Lb mass verses lb force gives me a head ache so I never use lb mass. I have not used a slug since school. I do have mechanics use a slugging wrench to tighten bolts. Does that count? |
I can deal with Nm and foot-pounds, but kilogram meters make me sick. Unfortunately, that seems to be here to stay.
