Because ethyl alcohol (ethanol) has as a lower density than water, its weight can vary from water or other liquids.
Here is a quick reference for commonly asked weights:
- 1 gallon of 200 proof ethyl alcohol = about 7 lbs.
- 5 gallon jug of 200 proof or 190 proof ethyl alcohol = about 33 lbs.
- 55 gallon drum of 200 proof or 190 proof ethyl alcohol (including the weight of the drum) = about 384 lbs.
