How Much Is 8 Ounces of Olive Oil in Fluid Ounces?
8 ounces of olive oil equals 8.40 fl oz. That's 226.80g, and Olive oil has a density of 216g per cup. Because ounces measure weight and fluid ounces measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 8 ounces of olive oil
- Convert ounces to grams: 8 × 28.35 = 226.80g
- 1 cup of olive oil = 216g
- 226.80g ÷ 216g/cup = 1.05 cups × 8 = 8.40 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.
