How Much Is 31.99 Ounces of Vegetable Oil in Cups?
Converting 31.99 ounces of vegetable oil to cups gives 4.16 cups. First convert to grams (31.99 oz = 906.90g), then divide by the density of vegetable oil (218g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 31.99 ounces of vegetable oil
- Convert ounces to grams: 31.99 × 28.35 = 906.90g
- 1 cup of vegetable oil = 218g
- 906.90g ÷ 218g/cup = 4.16 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.
