why do we measure mass in weight? if mass is how much space we take up then, how do we measure how much space we take up in weight? i mean newtons are the right tool of measurement for this right? if they are, why do we don't always use then instead? Many teachers have tried to make me understand, but i just can't.

Question

simple....
1.layman cant undrstand the meaning of newtton.
2.to measure mass a physical banace is req,which is not avaialable to every1 but spring balances are radily available to every1
3.to get weight mass has to be multiplied by "g= 9.8 ",which is difficult for every1
so with few reasons,the general publik is using wight units s Kg and will continue to do so,....
