Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 244g/cup × 8 = fluid ounces

Start with 3 ounces of milk
Convert ounces to grams: 3 × 28.35 = 85.05g
1 cup of milk = 244g
85.05g ÷ 244g/cup = 0.35 cups × 8 = 2.79 fluid ounces

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 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.

What is a Fluid Ounce?

There are 8 fluid ounces in a US cup and 128 fluid ounces in a US gallon. The UK fluid ounce is slightly smaller (28.413 ml vs 29.574 ml), so UK and US recipes using fluid ounces will differ slightly.
