How Much Is 20.5 Grams of Corn Syrup in Fluid Ounces?

20.5 grams of corn syrup equals 0.50 fl oz. Corn syrup has a density of 328g per cup. Because grams measure weight and fluid ounces measure volume, the result depends on the ingredient's density.

Formula and Step-by-Step

grams ÷ 328g/cup × 8 = fluid ounces
  1. Start with 20.5 grams of corn syrup
  2. 1 cup of corn syrup = 328g
  3. 20.5g ÷ 328g/cup = 0.06 cups × 8 = 0.50 fluid ounces

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Sticky liquids like corn syrup are easier to measure if you lightly oil the measuring cup first. The liquid will slide out cleanly.

Understanding the Units

What is a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

What is a Fluid Ounce?

Fluid ounces measure how much space a liquid takes up, while ounces (oz) measure weight. 1 fluid ounce of water weighs close to 1 oz, but for other liquids like honey or oil, the weight per fluid ounce is different.

Frequently Asked Questions

About 0.50 fl oz, based on corn syrup having a density of 328g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Divide the grams by 328 (grams per cup) to get cups, then multiply by 8 to get fluid ounces. For 20.5 grams: 20.5 ÷ 328 = 0.06 cups × 8 = 0.50 fl oz.
Weighing corn syrup on a kitchen scale is strongly recommended. It is thick and sticky, so it clings to measuring vessels. If you must measure by volume, lightly oil the measuring cup first so it slides out cleanly.
Temperature has a minimal effect on most cooking liquids. The density of corn syrup 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: 0.50 fl oz ÷ 8 = 0.0625 cups, then 0.0625 × 328g/cup = 20.5g. Or use the Fluid Ounces to Grams converter.
