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?

Answer:
mass is how much stuff you have (how many atoms or molecules)
weight is how ‘attractive’ stuff is to the closet huge thing (planet, natural satellite, star) this is determined by gravity (of the nearest huge thing).
on Earth mass is can stand in for weight and vice-versa.
this is because 10kg of stuff is being acted on by earth so the mass and weight can have the same name.
on the moon 1kg of gold has a mass of 1kg but a weight one sixth as much. (IIRC)
on Mars 1kg of gold is how many atoms of gold you have but it weighs 0.75 its weight on earth.
Kinda like inflation a dime is a dime, a dollar is a dollar, (mass) but a dime used to buy 10 candies… won’t buy anything in the current gravity (weight).
