What Is 3/4 of a Cup Doubled?
If you double 3/4 of a cup, you'll get 6/4 cups, which can be simplified as 3/2 cups or 1 1/2 cups. In decimals, 3/4 of a cup is .75 cups, and .75 doubled is 1.5 cups. Since a United States customary cup holds exactly 8 U.S. fluid ounces, 3/4 of a cup is exactly 6 ounces. When you double 3/4 of a cup, you'll get 12 U.S. fluid ounces. When following recipes, it is important to note that U.S. customary volume measurements are not the same as the British imperial system even though they share the same names for the volume units.
