mass vs weight

827 views

Conceptually I understand that mass is a measure of the amount of stuff present in an object, while weight is a measure of the force of gravity applied to that object. An object of a given mass will have a bigger weight on Earth than on the moon because Earth’s gravity is stronger. But… mass is determined by weighing an object on a scale. And there is a simple mathematical conversion between grams (mass) and pounds (weight), implying that they’re just different units for the same concept. So what gives? (Also this is a question that applies to so many fields, I had no idea which flair to apply.)

mass -> doesn’t change, its about the number of atoms of an object(in kg)

weight -> depends on which planet you are, it’s a force(in Newtons). It’s the mass multiplied by a constant for acceleration.

technically when we ‘measure the weight in kg’ of someone, we should actually say that we determine
the mass in kg by measuring the weight(it’s proportional, due to the gravitational constant already mentioned)
