Formula and Step-by-Step
- Start with 4 quarts of buttermilk
- 1 quart of buttermilk = 980g
- 4 × 980 = 3,920g
- Convert grams to ounces: 3,920 ÷ 28.3495 = 138.27 oz
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 Quart?
The quart gets its name from "quarter" (of a gallon). One US quart is about 5.7% smaller than 1 liter (946 ml vs 1,000 ml). Always use the exact unit your recipe specifies.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
