Frequently Asked Questions

How many grams in 1 cup of molasses?

About 315 grams, scoop-and-level for dry ingredients. Dark molasses, ~1.33 g/mL. 1 cup = 16 oz by weight.

How many grams in a tablespoon of molasses?

One US tablespoon (15 mL) of molasses is about 19.7 grams. A teaspoon is 6.56 g.

Why does molasses weigh more (or less) than water?

Its density differs from water's 1 g/mL: 1 cup of molasses weighs 315 g versus 237 g for water. Denser liquids (honey, syrup) weigh more per cup; oils weigh less.

How many cups is 100 g of molasses?

100 g ÷ 315 g/cup ≈ 0.32 cups - about a little less than a full cup. The reverse table on this page covers 25-1000 g.

Should I weigh or measure by volume?

Weighing is more accurate - volume measures vary with how you scoop, pack, and level, and brands differ by 5-15%. For cookies and cakes where ratios matter, grams are the professional standard. The tables here convert either direction.
