How Much Is 4 Ounces of Vegetable Oil in Cups?
4 ounces of vegetable oil equals 0.52 cups. That's 113.40g, 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 4 ounces of vegetable oil
- Convert ounces to grams: 4 × 28.35 = 113.40g
- 1 cup of vegetable oil = 218g
- 113.40g ÷ 218g/cup = 0.52 cups
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 Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
