So the Earth's gravity varies at different locations and if I record my mass using the the scales at these locations.
Won't the scales give a different value for my mass depending on location.
If the scales had done the calculation the value for the mass would not vary.
The scales will give a different value for mass becuase they are calibrated to a specific gravity. In localised regions of higher/lower gravity the reading will be off because your weight will change but the scales dont 'know' the gravity has changed.

The weight to mass calcualtion is just a constant multiplier that either has to be programmed in on a digital scale or the wheel has to be calibrated on an analogue scale.
