How Much Is 12 Ounces of Corn Syrup in Milliliters?
12 ounces of corn syrup equals 245.38 ml. Corn syrup has a density of 328g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
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.
Corn Syrup at Different Amounts
How corn syrup scales across common ounces measurements. Your amount (12 ounces) is highlighted.
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
What is a Milliliter?
A milliliter (ml) is a metric unit of volume equal to 1/1000 of a liter. It is the standard volume measurement for cooking in most countries outside the US. One cup equals approximately 236.588 milliliters.
About 245.38 ml, 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.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 328 (grams per cup), then multiply by 236.588 to get milliliters. For 12 ounces: 12 × 28.3495 = 340.19g, then 340.19 ÷ 328 = 1.04 cups × 236.588 = 245.38 ml.
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: 245.38 ml ÷ 236.588 = 1.03718 cups, then 1.03718 × 328g/cup = 340.19g, then 340.19g ÷ 28.3495 = 12 ounces. Or use the Milliliters to Ounces converter.
