Mass explanation: I’ve always been told that mass was not the same as weight, and that grams are the metric unit of mass. But grams are a measurement of weight, so am I stupid, was it was explained to me wrong, or is science just not make sense?

You go into a region of space where there is almost no gravity, you will have no weight. If you tried to stand on a scale, it would read zero.
You still have just as much mass as you did before, but now that gravity is gone you have no weight because there’s no gravity pulling that mass down.
If you went to some massive planet with strong gravity, you’d feel waaaay heavier, but your mass wouldn’t change.
What a scale does is measure your weight – the force of gravity pulling you down. Because we are all on Earth, you can calculate your mass based on your weight. A scale can therefore measure both at the same time. However, grams are *technically* a measure of mass.
