150 grams of molasses equals 0.11 qt. Molasses has a density of 340g per cup. Because grams measure weight and quarts measure volume, the result depends on the ingredient's density.

Formula and Step-by-Step
grams ÷ 340g/cup × 0.25 = quarts
Start with 150 grams of molasses
1 cup of molasses = 340g
150g ÷ 340g/cup = 0.44 cups × 0.25 = 0.11 quarts
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.
Molasses at Different Amounts
How molasses scales across common grams measurements. Your amount (150 grams) is highlighted.
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.
What is a Quart?
US and UK quarts differ significantly. A US quart is 946 ml while a UK (imperial) quart is 1,137 ml, about 20% larger. Recipes from British cookbooks using quarts will need adjustment for US measuring equipment.
About 0.11 qt, based on molasses having a density of 340g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Divide the grams by 340 (grams per cup) to get cups, then multiply by 0.25 to get quarts. For 150 grams: 150 ÷ 340 = 0.44 cups × 0.25 = 0.11 qt.
Weighing molasses on a kitchen scale is strongly recommended. It is thick and sticky, so it clings to measuring vessels. If you must measure by volume, lightly oil the measuring cup first so it slides out cleanly.
Temperature has a minimal effect on most cooking liquids. The density of molasses changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 0.11 qt ÷ 0.25 = 0.441176 cups, then 0.441176 × 340g/cup = 150g. Or use the Quarts to Grams converter.
