Cups to Pounds Converter
Convert cups to pounds and pounds to cups for common baking ingredients using density-based weight and volume math.
Cups to Pounds for Baking Ingredients
Cups measure volume. Pounds measure mass. To convert between them you need ingredient density. This tool uses common food densities to estimate how many pounds are in a cup, or how many cups are in a pound. Pair it with the Cooking Measurement Converter or Cups to Ounces Converter.
Conversion Formula
$$\text{mass} = \text{density} \times \text{volume}$$
Density is entered in kg/m³. One US cup is 236.588 mL. One pound is 453.592 g. The tool reports both pounds per cup and cups per pound for quick recipe scaling.
Example
All-purpose flour is about 530 kg/m³. One cup weighs roughly 0.28 lb, so 2 cups is about 0.56 lb.
Frequently Asked Questions
Why does butter convert so cleanly?
Butter density is close to water and many recipes treat 1 cup as about half a pound, which makes mental math easy.
Should I weigh flour instead of scooping cups?
Weight is more consistent for compressible ingredients like flour. Cups can vary with scooping style and packing.
Can I convert pounds to cups?
Yes. Switch direction to pounds to cups and enter the weight you have.
What if my ingredient is not listed?
Select Custom Ingredient and enter density in kg/m³ from a nutrition label or food density table.
