Why do we use a common balance to measure the mass of an object instead of a spring balance? Can we determine the mass of an object by using a spring balance?

Explanation

Spring balance is used for measuring the weight of an object, `w = m xx g`.
If we know the value of acceleration due to gravity (g) at that place, we can determine the mass of the object as, m = w/g
But the value of acceleration due to gravity on the surface of the earth changes from place to place. So, we use a common balance to measure the mass of an object instead of a spring balance.
