A gallon of molasses weighs approximately 11.73 pounds.

A gallon of molasses weighs around 11.73 pounds (5.32 kg), which is significantly heavier than a gallon of water at 8.34 pounds. This weight difference is due to molasses' high density, which comes from its sugar content and thick, viscous nature. The exact weight can vary slightly depending on the specific type and sugar concentration of the molasses.

Weight comparison of common liquids per gallon

Liquid Weight (lbs) Weight (kg)
Molasses 11.73 5.32
Water 8.34 3.78
Honey 12.0 5.44
Vegetable oil 7.7 3.49

Factors affecting molasses weight

  • Type: Blackstrap molasses is denser than light molasses
  • Temperature: Warmer molasses weighs slightly less due to expansion
  • Sugar content: Higher sugar concentration increases weight

Common uses for measuring molasses by weight

  1. Baking recipes requiring precise measurements
  2. Industrial applications for consistent mixing ratios
  3. Shipping and transportation calculations
