In some contexts, it is OK. They are equivalent within a certain context,
but not in general.
If a scale compares one mass to another, then it is effectively measuring
mass, and is independent of gravity field strength. If it compares one force
against another, such as weight against spring force it is effectively
measuring weight, which is a force.
It can be seen as a property within a certain context, but not in general.
