How Much Is 40 Fluid Ounces of Molasses in Grams?
40 fluid ounces of molasses weighs 1,700.00 g. This is based on molasses having a density of 340g per cup. Because fluid ounces measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 40 fluid ounces.
Formula and Step-by-Step
- Start with 40 fluid ounces of molasses
- 1 fluid ounce of molasses = 42.5g
- 40 × 42.5 = 1,700g
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.

Understanding the Units
What is a Fluid Ounce?
There are 8 fluid ounces in a US cup and 128 fluid ounces in a US gallon. The UK fluid ounce is slightly smaller (28.413 ml vs 29.574 ml), so UK and US recipes using fluid ounces will differ slightly.
What is a Gram?
Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.
