Sport Pilot;

Newtons (N): force (and weight which is the force of gravity)
kilograms (kg): mass

When weight is "measured" in grams/kilograms (or ounces/pounds), it is a way of simplifying things, although it is wrong. The mass of one kilogram will have a gravity of roughly 9.80665 Newtons. It has become a "bad habit" to say that the weight is 1 kg. The weight is 9.80665 N, and the mass is 1 kg.

Actually both are used for both force and mass. However Newtons and Slugs are simply adjusted for the force of gravity. 1 Newton is equal to 9.8 Kg, and one Slug is 32.2 pounds.
