# 12 fluid ounces: How Much Do They Weigh?

The density of the substance affects how much 12 fluid ounces weigh. In contrast to ounces, which are used to measure weight, fluid ounces are used to measure volume (i.e. how much space something takes up). As an illustration, one fluid ounce of pure water, which has a lower density than milk, weighs one ounce, but 12 fluid ounces of nonfat milk weigh 12.96 fluid ounces.

While 12 fluid ounces of roasted coffee beans weigh only 5.41 ounces, the same amount of granulated sugar weighs 10.63 ounces. A 12-fluid-ounce Coke can’s contents weigh around 7.64 ounces.

It takes two tablespoons or 0.03 litres to make one fluid ounce. Therefore, 24 teaspoons or 0.35 litres are the volume equal of 12 fluid ounces.
