Answer:
The mass of an object is measured by use of a balance (not a scale). The balance works by comparing the weight of the object with the weight of a known mass, or set of known masses that have been compared against a standard.
Therefore, although a balance requires some amount of gravity to work, it gives the correct answer for the mass of the object without regard to whether the gravitational field is or is not not a standard value, or is even known at all.
On the Moon, or some other planet, a kilogram mass would measure at 1 kg if placed on a balance.
Scales measure force against a known standard, so scales measure weight, not mass. Although mass can be calculated (sometimes within the scale itself) if the exact strength of the gravitational field is known. But it’s a derived value, not a direct measurement.
