Official Conversion Factor: 1 Liter = 0.264172 U.S. Gallon (see 27 CFR 19.582) For the examples above, the conversion from liters to U.S. units was made before multiplying by the number of cases and the quantity in U.S. units is rounded to the sixth decimal, as required under §19.582(a). If the conversion from liters to U.S. units is made after multiplying by the number of cases, the quantity in U.S. units must be rounded to the nearest hundredth (i.e., second decimal) see §19.582(b). Once converted to wine gallons, the proprietor must determine the proof gallons of spirits in cases (see 27 CFR 30.52). |
For information on how to calculate the proof gallons of distilled spirits, see FAQ S2.
