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.)

Scales that provide a mass result only work in the special case of roughly 1g. Otherwise it will need to be recalibrated human experience has been mostly confined to our 1G working environment and so this has not proven to be an manageable problem thus far.
