How Much Is 1 Ounce of Vegetable Oil in Cups?
1 ounce of vegetable oil equals 0.13 cups. That's 28.35g, and Vegetable oil has a density of 218g per cup. Because ounces measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 1 ounce of vegetable oil
- Convert ounces to grams: 1 × 28.35 = 28.35g
- 1 cup of vegetable oil = 218g
- 28.35g ÷ 218g/cup = 0.13 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Oils are lighter than water, so the same volume weighs less. Pour slowly into the measuring cup for accuracy, and wipe any drips from the outside before reading.

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 Cup?
The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.
