How Much Is 3 Cups of Molasses in Grams?
3 cups of molasses weighs 1,020.00 g. This is based on molasses having a density of 340g per cup. Because cups measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 3 cups.
Formula and Step-by-Step
- Start with 3 cups of molasses
- 1 cup of molasses = 340g
- 3 × 340 = 1,020g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.
Molasses at Different Amounts
How molasses scales across common cups measurements. Your amount (3 cups) is highlighted.
For reference, 3 cups of molasses (1,020g) is close in weight to a pineapple (1,000g).

Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
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.
