Formula and Step-by-Step

fluid ounces × 27.25g/fl oz ÷ 28.3495g/oz = ounces
  1. Start with 4 fluid ounces of vegetable oil
  2. 1 fluid ounce of vegetable oil = 27.25g
  3. 4 × 27.25 = 109g
  4. Convert grams to ounces: 109 ÷ 28.3495 = 3.84 oz

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.

Frequently Asked Questions

About 3.84 oz, based on vegetable oil having a density of 218g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of fluid ounces by 27.25 (grams per fluid ounce for vegetable oil), then divide by 28.3495 to convert grams to ounces. For 4 fluid ounces: 4 × 27.25 = 109g, then 109 ÷ 28.3495 = 3.84 oz.
For the most accurate results, weigh vegetable oil on a kitchen scale. If measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height.
Temperature has a minimal effect on most cooking liquids. The density of vegetable oil changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 3.84 oz × 28.3495 = 109g, then 109g ÷ 27.25 = 4 fluid ounces. Or use the Ounces to Fluid Ounces converter.
