How Much Is 4.5 Ounces of Molasses in Fluid Ounces?
4.5 ounces of molasses equals 3.00 fl oz. That's 127.57g, and Molasses has a density of 340g per cup. Because ounces measure weight and fluid ounces measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 4.5 ounces of molasses
- Convert ounces to grams: 4.5 × 28.35 = 127.57g
- 1 cup of molasses = 340g
- 127.57g ÷ 340g/cup = 0.38 cups × 8 = 3.00 fluid ounces
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.

Understanding the Units
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.
What is a Fluid Ounce?
Fluid ounces measure how much space a liquid takes up, while ounces (oz) measure weight. 1 fluid ounce of water weighs close to 1 oz, but for other liquids like honey or oil, the weight per fluid ounce is different.
