Cups to Pounds Converter
Convert a volume measurement in cups into weight in pounds and ounces, using typical densities for common baking and cooking ingredients.
How this converter works
Cups measure volume, but pounds measure weight, so converting between them depends on how dense the ingredient is. A cup of flour weighs much less than a cup of honey because flour has air pockets and honey is thick and compact.
This calculator uses standard reference densities (grams per cup) published by culinary sources such as the USDA and major baking brands for common ingredients like flour, sugar, butter, and rice. It multiplies your entered number of cups by the ingredient’s typical weight per cup to give pounds, ounces, and grams.
- Flour is measured by the “spoon and level” method, which is the most common home baking convention.
- Packed brown sugar assumes it is pressed firmly into the cup, as most recipes intend.
Because ingredient density can vary slightly by brand, humidity, and how tightly it is packed, treat results as a close estimate for recipe planning rather than a lab-precise measurement.
