So where do you decide is the correct location to give the accurate reading for both mass and weight.
In other words where is the place it is all nailed down.
Who decided and why.
Mass never changes.

The value of 'g' used to calculate weight is taken from an average of different 'g' values from different points.


This is the reason we assign a standard value for gravity.

Its also the same reason we assign a standard value for atmospheric pressure, that vaires but for the sake of ease of calulation a value is chosen that minimises error at all locations.
