Understanding the Units

What is a Fluid Ounce?

A US fluid ounce (fl oz) is a unit of volume equal to 29.574 milliliters or 1/8 of a cup. It measures liquid volume and should not be confused with the ounce (oz), which measures weight.

What is a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 492.00 g, 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.
Multiply the number of fluid ounces by 41 (grams per fluid ounce for corn syrup). For 12 fluid ounces: 12 × 41 = 492.00 g.
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: 492.00 g ÷ 41 = 12 fluid ounces. Or use the Grams to Fluid Ounces converter.
