I have tried looking around the internet for an answer - but I can only find articles that explain what the clutch on a drill does.
I am very familiar not only with what they do but also with how they operate. I have always wondered, however, what the units for the numbers are. They don't seem to be anything standard.
My drill has a max torque of 725lbf-in. I have tried converting that into all of the different units for torque I can find, but none of them result in a 24 (my max torque setting), or anything in that range.
