How Much Is 1.5 Gallons of Molasses in Grams?
1.5 gallons of molasses equals 8,160.00 g. Molasses has a density of 340g per cup (5,440g per gallon), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 1.5 gallons of all-purpose flour would be 3,003.84 g.
Formula and Step-by-Step
- Start with 1.5 gallons of molasses
- 1 gallon of molasses = 5,440g
- 1.5 × 5,440 = 8,160g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Sticky liquids like molasses are easier to measure if you lightly oil the measuring cup first. The liquid will slide out cleanly.

Understanding the Units
What is a Gallon?
The US gallon (3,785 ml) and UK imperial gallon (4,546 ml) are very different. A UK gallon is about 20% larger. A gallon of milk in the US is 3.785 liters, while a UK gallon of milk would be 4.546 liters.
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
