Interesting.
A spring (torsion) scale measures the deformation of such spring to indicate weight. The deformation is based on the mass over the spring, compressing it by the gravity pull. "Calibration" means to use a standard known weight over the spring, and adjust the dial to show exactly the value of such mass. Other intermediary standard weights are used to make sure the scale indication still correct after calibration. Industrial and lab scales are supplied with calibration weights and more precise ones could be bought to produce frequent calibrations. No industry or "pharmacy" would use a scale that is out of calibration according to procedures stated and followed. It is imperative for an industry to calibrate their equipment very often, they may be losing money by not doing so, it worth the calibration cost. Some equipment can not even be calibrated in the field, some need to be sent to calibration labs, where they use super-standards based on NIST, and even those super-standards calibrators need calibration also. So, you can be sure, an industrial or lab calibrated scale located anywhere in the globe would indicate the same weight for the same pound of mass. No doubt about that. Thinking differently is just demonstrating not knowing about how this things work. A 499g piece of stainless steel will not change its mass based on temperature, humidity, air pressure, it must show 499g on the Equator or on the Poles. Some electronic scales has self-calibrating features, they do pretty good within certain range. In the past I worked with load cells, when you work with those you start to understand about all other scales, since they are also used to measure force of deformation in general, bridges steel beams, arcs, building floor beams, vehicles long frames like long trucks, trains, even rockets structures - pounds related to nothing is the most common measurements on those, just related to deformation of resting state.
