*Approximate refractive solids shown as 100 − moisture for consistency with the Beekeeper Calc converter. The refractive-index column follows the Chataway honey-moisture table used by the live tool.
Temperature compensation, calibration, and instrument scale matter. Confirm your instrument instructions and re-check representative, well-mixed honey.
