Alcohol by Weight (ABW) 

A measurement of the alcohol content of a solution in terms of the percentage weight of alcohol per volume of beer. For example: 3.2 percent alcohol by weight equals 3.2 grams of alcohol per 100 centiliters of beer. This measure is always lower than Alcohol by Volume. To calculate the approximate alcohol content by weight, subtract the final gravity from the original gravity and divide by 0.0095. For example: 1.050 – 1.012 = 0.038/0.0095 = 4% ABW.
