## Main Question or Discussion Point

I'm a bit curious and confused. In genereal problems, when they say that something weighs #Newtons, can you just find the mass by dividing by gravity?

Yes, divide the weight in Newtons by g, [tex]9.8 \frac{m}{s^2}[/tex] to get the mass in kg. This of course assumes that you are on the surface of the earth.

...and in a place where G = 9.8. It varies by more than most people realize (more than I realized until someone brought it up a month ago here).Originally posted by Integral
