How scales work compared to balances?

In simple terms, the following can be said:

A balance is used to caluculate the mass of an object in comparison to a known weight.

A scale is used to measure the force exerted on a mass by the gravity of the earth, then to convert that measurement into a calculation of the object's mass.

Therefore, we actually measure mass, not weight.

A scale provides much more precise calculations than does a balance.
