TTB Gauging Manual and Tables
Note: The "Gauging Manual" (27 CFR Part 30) and its tables relate primarily to gauging spirits at distilled spirits plants (DSPs).  However, the manual's conversion tables Nos. 4, 5, and 6 are frequently used by all regulated entities including manufacturers of nonbeverage products (MNBPs).  (The regulations and tables can be downloaded directly from this website without searching for them on the TTB website)
