Sec.  31.231  Conversion between metric and U.S. units.

    When liters are converted to wine gallons, the quantity in liters 
shall be multiplied by 0.264172 to determine the equivalent quantity in 
wine gallons. Cases containing the same quantity of spirits of the same 
proof in metric bottles may be converted to U.S. units by multiplying 
the liters in one case by the number of cases to be converted, as 
follows:
    (a) If the conversion from liters to U.S. units is made before 
multiplying by the number of cases, the quantity in U.S. units shall be 
rounded to the sixth decimal.
    (b) If the conversion is made after multiplying by the number of 
cases, the quantity in U.S. units shall be rounded to the nearest 
hundredth.

Once converted to wine gallons, the proof gallons of spirits in cases 
shall be determined as provided in 27 CFR 30.52.
