With the obvious standard of comparison (weight under Earth surface
gravity), the kilogram is larger than the Newton.

1 kg ~= 9.8 Newtons

With my background in the U.S. system, I tend to think of a kilogram
as about 2 pounds and a Newton as about a quarter pound when I want
to visualize the respective quantities.

Perhaps you were thinking along the lines of:

F = m * g
N = kg * 9.8 (questionable notation)
Therefore a Newton is 9.8 kilograms. (fallacious)
Therefore 9.8 Newtons is 1 kilogram. (correct)
