How Much Is 5 Ounces of Vegetable Oil in Fluid Ounces?
5 ounces of vegetable oil equals 5.20 fl oz. Vegetable oil has a density of 218g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 5 ounces of vegetable oil
- Convert ounces to grams: 5 × 28.35 = 141.75g
- 1 cup of vegetable oil = 218g
- 141.75g ÷ 218g/cup = 0.65 cups × 8 = 5.20 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?
The US fluid ounce (29.574 ml) and the UK fluid ounce (28.413 ml) are different sizes. The UK version is about 4% smaller. This means a UK recipe calling for 8 fl oz gives you 227 ml, while 8 US fl oz gives you 237 ml. The difference is small per ounce but adds up in larger quantities.
