A weighing system for use in retail transactions comprises a weighing platform characterized by a weighing-platform weight range corresponding to a first level of precision and extending from a zero weight-value to a weighing-platform maximum value. A controller is configured to open and operate a virtual scale that uses the weighing platform and is characterized by a virtual-scale weight range corresponding to a second level of precision and smaller than the weight-platform weight range. Opening the virtual scale includes setting, at a first time, a respective virtual zero-weight value and a respective virtual-scale maximum value for the virtual-scale weight range. Operating the virtual scale includes calculating, at a second time, a current-item weight for a current item added to the weighing system after the first time.
