Converting 4 ounces of molasses to milliliters gives 78.91 ml. First convert to grams (4 oz = 113.40g), then divide by the density of molasses (340g per cup). Each ingredient fills a different volume at the same weight.
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?
Most kitchen measuring cups outside the US are marked in milliliters. A standard metric cup is 250 ml. When converting American recipes, 1 US cup = 236.588 ml.
About 78.91 ml, based on molasses having a density of 340g 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 340 (grams per cup), then multiply by 236.588 to get milliliters. For 4 ounces: 4 × 28.3495 = 113.40g, then 113.40 ÷ 340 = 0.33 cups × 236.588 = 78.91 ml.
Weighing molasses 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 molasses 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: 78.91 ml ÷ 236.588 = 0.333524 cups, then 0.333524 × 340g/cup = 113.40g, then 113.40g ÷ 28.3495 = 4 ounces. Or use the Milliliters to Ounces converter.
