5 ounces of molasses equals 98.63 ml. That's 141.75g, and Molasses has a density of 340g per cup. Because ounces measure weight and milliliters measure volume, the result depends on the ingredient's density.
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.
Molasses at Different Amounts
How molasses scales across common ounces measurements. Your amount (5 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?
Milliliters measure volume and are used worldwide for cooking and baking. For water at room temperature, 1 ml weighs approximately 1 gram, but this relationship does not hold for other ingredients.
About 98.63 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 5 ounces: 5 × 28.3495 = 141.75g, then 141.75 ÷ 340 = 0.42 cups × 236.588 = 98.63 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: 98.63 ml ÷ 236.588 = 0.416905 cups, then 0.416905 × 340g/cup = 141.75g, then 141.75g ÷ 28.3495 = 5 ounces. Or use the Milliliters to Ounces converter.
