Not knowing exactly how to represent it I've just been using "g" for gram like "2000 g". I've been wondering what is the proper way to represent sharpness readings.
Yes Mr. Grepper! "gf" – gram-force, is a non-standard gravitational unit of force, which does not comply with the SI Metric System used outside the US.
The SI unit of force is newton (N). The conversion factor is following:
1 gf = 0.00981 N.
The figure 9.81 m/s2 is average gravity acceleration on the Earth surface.
So, the BESS sharpness 2000 gf = 19.62 N. Roughly we can say that 2000 gf ≈ 20 N.
In my understanding the gram-force unit is the proper way to represent BESS readings within the US, for the rest of the world the conversion to newton should be stated in brackets.
P.S.: In UK "engineering" systems pound-force unit ("lbf") can be used.
