Temperature Correction

True
Proof

TTB Table 1 correction · Corrected to 60°F reference

Input Method

Hydrometer reading + spirit temp → true proof at 60°F, straight off TTB Table 1 (same as the Pass Tracker).

Apparent Proof

Hydrometer reading at actual temp · 51–100 or 151–204

Temperature

Spirit temp at time of reading · 51–80°F (to 90°F above 151)

Temp Unit

For lab-grade accuracy. Enter specific gravity at observed temperature. Uses the OIML ethanol-water density model corrected to 60°F.

Specific Gravity

0.7893 – 1.000

Temperature

Temp at SG reading

Temp Unit

Convert ABV% to US Proof. US Proof = ABV × 2. Also corrects to 60°F if a temperature is provided.
