(Note that it is not the specific weight of the specific object which is operationally defined, but the process for arriving at it.his is especially so in the sciences, where most (if not all) formal definitions (as distinct from arbitrary naming) must be operational definitions or traceable to operational definitions. Operational definitions are particularly important in the physical sciences.
