Newtons are politically correct for force as opposed to g or kg which are mass units.
Think you'll find most commercial torque wrenches calibrated in some form of kg-m.

Subject: [Indoor_Construction] Re: Motor Weight, Size Density, Torque ?
My kids in Science Olympiad helicopters this year kept ribbing me about using english units for torque and rubber dimensions. I found in their supplies an old IMS torque meter and we calibrated its reading. Low and behold, the meter dial numbers corresponded to milli-Newton-meters (that is one one thousandth of a N-m)! Lew Gitlow was ahead of his time. Just in case anyone wants to convert to metric, one oz-in is 7.06 milli-N-m. For the aspiring F1D and LPP fliers, on average a good F1D motor will wind to just over 4 milli-N-m while a good LPP motor will take a bit under 8 milli-N-m.
I may just make new dials for my torque meters in the near future. A torque meter that reads to 1.4 oz-in will read to 10 milli-N-m (actually .99 but 1% accuracy is good enough) in metric.
