I want to compute the rate of a spring from g/in to N/M. Does anyone know how to do that?

To verify, is that gram/inch to Newton/meter?

if so, that would have a conversion factor of 0.3860886

1 gram = 1/101.971621 Newton
1 inch = 0.0254 meter

gram/inch * (1/101.971621 / 0.0254) = Newton/meter
gram/inch * 0.3860886 = Newton/meter

I am not sure I completely trust this reply. How can 1 gram be equated to a value of Newtons, since a gram is a unit of mass and a Newton is a unit of force? To convert a gram value to newtons, there would need to be an acceleration factor as well (i.e. "g x m/s2". 1 Newton is about the value of a little over 100 grams under the acceleration of Earths gravity (9.8m/s2, or 1g), so maybe that is what was meant. Granted, the question is odd too. The only meaning I can think of for "g/in" is grams/inch, since one "gravity/inch" makes little sense, but that mixes metric and English units and in any case still does not match units with a newton/meter.
