Formula and Step-by-Step

(pounds × 453.59g/lb) ÷ 245g/cup ÷ 16 = gallons
  1. Start with 391 pounds of buttermilk
  2. Convert pounds to grams: 391 × 453.59 = 177,354.62g
  3. 1 cup of buttermilk = 245g
  4. 177,354.62g ÷ 245g/cup = 723.90 cups ÷ 16 = 45.24 gallons

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.

Pounds are the standard weight unit for buying ingredients in the US. A standard bag of flour is 5 pounds (2,268g) and a standard bag of sugar is 4 pounds (1,814g).

What is a Gallon?

For large-batch cooking, 1 US gallon is approximately 3.8 liters. The imperial gallon (4.5 liters) is no longer commonly used in the UK for cooking, as most modern British recipes use metric measurements.

Frequently Asked Questions

About 45.24 gal, 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), then divide by 16 to get gallons. For 391 pounds: 391 × 453.592 = 177,354.62g, then 177,354.62 ÷ 245 = 723.90 cups ÷ 16 = 45.24 gal.
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: 45.24 gal × 16 = 723.896 cups, then 723.896 × 245g/cup = 177,354.62g, then 177,354.62g ÷ 453.592 = 391 pounds. Or use the Gallons to Pounds converter.
