How Much Is 3 Cups of Molasses in Pounds?
3 cups of molasses weighs 2.25 lb. This is based on molasses having a density of 340g per cup. Because cups measure volume and pounds 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
- Convert grams to pounds: 1,020 ÷ 453.592 = 2.25 lb
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.
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 Pound?
A pound (lb) is a US customary unit of weight equal to 453.592 grams or 16 ounces. It is used for larger quantities of ingredients like flour, sugar, and meat.
