How Much Is 1 Cup of Molasses in Ounces?
1 cup of molasses equals 11.99 oz. 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 4.41 oz.
Formula and Step-by-Step
- Start with 1 cup of molasses
- 1 cup of molasses = 340g
- 1 × 340 = 340g
- Convert grams to ounces: 340 ÷ 28.3495 = 11.99 oz
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 (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 an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
