Alcoholmetric Tables & Temperature Correction

Using a thermal expansion model — what a hydrometer would show at another temperature, and conversely, recovering true ABV from an apparent reading.

Result

Apparent ABV at this temperature—
Difference from true—
Based on a linear thermal expansion approximation — official OIML tables differ slightly. See Theory.

Result

True ABV (at 20°C)—
Correction magnitude—
