Beer measurement study
Use measured original gravity and final gravity to see a standard ABV approximation and the gravity difference behind it.
Local-only calculation, clear assumptions, and no production instructions.
The calculator takes corrected original gravity minus final gravity and multiplies it by the displayed 131.25 approximation. It is an estimate, not laboratory analysis of a finished beverage.
For a corrected original gravity of 1.050 and final gravity of 1.010, the displayed estimate is approximately 5.25% ABV. Recheck units and readings before recording or acting on it.

Enter original gravity and final gravity as measured with your instrument, along with the relevant temperature details when needed.
Instrument calibration, temperature, fermentation behaviour, dissolved material, and measurement quality can affect the result.
No. The calculation and CSV or PDF export stay in your browser.
No. It is a measurement study, not a recipe or a process guide.
No. Food safety, sanitation, contamination, and equipment suitability need separate verification.
Yes. CSV and PDF exports use the same values and assumptions displayed by the calculator.
No. Rules differ by jurisdiction and must be checked with an appropriate local source.
No. Compare it with a suitable instrument, your documented measurements, and the instructions for that instrument.
Record the entered values, units, instrument, calibration temperature, date, and any observed batch conditions.
The models use simplified arithmetic and cannot include every characteristic of an actual batch or measurement method.
