How Much Is 12 Ounces of Maple Syrup in Milliliters?
12 ounces of maple syrup equals 257.97 ml. That's 340.19g, and Maple syrup has a density of 312g per cup. Because ounces measure weight and milliliters measure volume, the result depends on the ingredient's density.
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 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 257.97 ml, based on maple syrup having a density of 312g 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 312 (grams per cup), then multiply by 236.588 to get milliliters. For 12 ounces: 12 × 28.3495 = 340.19g, then 340.19 ÷ 312 = 1.09 cups × 236.588 = 257.97 ml.
Weighing maple 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 maple 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: 257.97 ml ÷ 236.588 = 1.09037 cups, then 1.09037 × 312g/cup = 340.19g, then 340.19g ÷ 28.3495 = 12 ounces. Or use the Milliliters to Ounces converter.
