85 grammes, or about 0.2 pounds, is the same as three ounces. This is a “weight measurement,” which is a dry measurement. 90 millilitres, or 6 tablespoons, are equal to 3 fluid ounces. This is a measurement of liquid, which is also known as a “volume measurement.”
Ounces of liquid can also be changed to cups. One cup is 8 ounces, which is half a pint. Three ounces is 3/8 of a cup. Also, when measuring dry ingredients, 3 ounces can be worth different amounts of weight depending on what is being measured. For example, 3 ounces of flour or powdered sugar would weigh a little less than 3 ounces of a more dense sugar, like brown sugar.
