How Much Is 3 Cups of Molasses in Ounces?
3 cups of molasses weighs 35.98 oz. This is based on molasses having a density of 340g per cup. Because cups measure volume and ounces 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 ounces: 1,020 ÷ 28.3495 = 35.98 oz
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 (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 an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
