Formula and Step-by-Step

(pounds × 453.59g/lb) ÷ 245g/cup = cups
  1. Start with 311 pounds of buttermilk
  2. Convert pounds to grams: 311 × 453.59 = 141,067.23g
  3. 1 cup of buttermilk = 245g
  4. 141,067.23g ÷ 245g/cup = 575.78 cups

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.

Frequently Asked Questions

About 575.78 cups, based on buttermilk having a density of 245g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert pounds to grams (1 pound = 453.592g), then divide by 245 (grams per cup). For 311 pounds: 311 × 453.592 = 141,067.23g, then 141,067.23 ÷ 245 = 575.78 cups.
For the most accurate results, weigh buttermilk on a kitchen scale. If measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height.
Temperature has a minimal effect on most cooking liquids. The density of buttermilk 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: 575.78 cups × 245g/cup = 141,067.23g, then 141,067.23g ÷ 453.592 = 311 pounds. Or use the Cups to Pounds converter.
