Grams to Cups: Molasses
If your recipe is written in cups but your scale reads grams — or the other way round — this page solves the conversion for molasses. One cup of molasses weighs about 337 grams, which works out to a density of 1.42 g/ml. From there, half a cup is roughly 169 g, a quarter cup about 84 g, and one tablespoon about 21 g.
Converting between weight and volume depends on density, and density is specific to each ingredient: a cup of molasses does not weigh the same as a cup of flour or sugar. That is why this tool uses the measured density of molasses, taken from the USDA FoodData Central database, rather than a one-size-fits-all figure.

How to measure molasses accurately
For molasses, spoon or pour it into the cup and level the top. Brown sugar is the exception — pack it down firmly into the cup unless the recipe says otherwise, because it traps air and would otherwise come up short on weight.
Weighing in grams removes any doubt about how firmly the sugar is packed, which is especially helpful in delicate recipes.
