How Much Is 1 Ounce of Olive Oil in Fluid Ounces?
1 ounce of olive oil equals 1.05 fl oz. That's 28.35g, 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 1 ounce of olive oil
- Convert ounces to grams: 1 × 28.35 = 28.35g
- 1 cup of olive oil = 216g
- 28.35g ÷ 216g/cup = 0.13 cups × 8 = 1.05 fluid ounces
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.

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.
