Is 70 kg my weight or mass?

Answer
When you say "70 kg," you're technically referring to your mass, not your weight. Mass is the amount of matter in your body and remains constant regardless of location. Weight, however, is the force exerted by gravity on your mass and is properly measured in newtons. In everyday conversation, people use "weight" and "mass" interchangeably, but scientifically, your mass is 70 kg, while your weight would be about 686 N on Earth.
