A pint of sour cream contains sixteen ounces of liquids. An ounce can be used to measure both weight and liquid volume (fluid ounces). Interestingly, a pint of sour cream weights 16 ounces as well.
One should not mix an ounce of net weight with an ounce of volume. 16 fluid ounces of water have a net weight of 16 ounces, whereas 16 fluid ounces of molasses are more dense and weigh 24 ounces. The British fluid ounce is slightly larger than the American equivalent, which is 1.04 fluid ounces. A fluid ounce is equivalent to 29.57 millilitres.
