How Much Is 557 Cups of Buttermilk in Pounds?
557 cups of buttermilk weighs 300.85 lb. This is based on buttermilk having a density of 245g per cup. Because cups measure volume and pounds measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 557 cups.
Formula and Step-by-Step
- Start with 557 cups of buttermilk
- 1 cup of buttermilk = 245g
- 557 × 245 = 136,465g
- Convert grams to pounds: 136,465 ÷ 453.592 = 300.85 lb
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.

Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is a Pound?
The abbreviation "lb" comes from the Latin word "libra." One pound equals exactly 453.59237 grams. For rough mental math, 1 pound is slightly less than half a kilogram.
