The weight of a gallon of milk is only slightly greater than a gallon of water, about 3% more. A US gallon with 2% milkfat weighs about 8.4 pounds, compared to 8.6 pounds for "whole milk" and 8.35 pounds for a gallon of water.
Milk is 87 % water, thus a gallon of milk will not differ from milk much.
The 8.6 lbs/gal factor (whole milk) is correct. The weight increases as fat is removed.
Milk : 8.6 lb/gallon
Condensed milk : 9.4 lb/gallon
Cream 8.28 lb/gallon
