How Much Is 1 Cup of Molasses in Pounds?
1 cup of molasses equals 0.75 lb. Molasses has a density of 340g per cup (340g per cup), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 1 cup of all-purpose flour would be 0.28 lb.
Formula and Step-by-Step
- Start with 1 cup of molasses
- 1 cup of molasses = 340g
- 1 × 340 = 340g
- Convert grams to pounds: 340 ÷ 453.592 = 0.75 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.
Molasses at Different Amounts
How molasses scales across common cups measurements. Your amount (1 cup) is highlighted.
For reference, 1 cup of molasses (340g) is close in weight to a can of soda (355g).

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.
