Temperature-corrected approximate SG
Hall polynomial correction factor in Fahrenheit; corrected=reading×CF(sample)/CF(calibration).
Correction (gravity points)
Hall polynomial correction factor in Fahrenheit; corrected=reading×CF(sample)/CF(calibration).

Assumptions & limits
Assumptions & limits
- Water-density empirical correction only; cool near calibration temperature for reliable readings, not a proof/alcohol hydrometer correction. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints.
