In the kitchen, a cup is a unit of measurement for volume that is used to figure out how much of dry ingredients, like chopped vegetables, or liquid ingredients, like milk, to use (fluid measurement). It is common in many countries, especially those that used to be part of the British Empire, like the United States and most members of the Commonwealth of Nations. It is also common in countries that tried to be like the British, like Japan. It happens a lot in places that used to be part of the British Empire.
Both the Imperial and US systems of units employ a fluid ounce as a volume unit. Imperial fluid ounce = 1/160 imperial gallon, 1/20 imperial pint, or 8 fluid dramas. A fluid ounce is 1,734 cubic inches or 28.4130625 milliliters. This amount of water weighs close to 1 avoirdupois ounce (one ounce heated to 62°F (16.7°C) and measured with brass weights in air).
One cup may contain a total of 8 ounces of liquid in the United States. One cup is equal to 10 ounces of fluid measurement in the United Kingdom.
1 US cup (236.6mL) Equals 8 US fluid ounces
1 UK cup (284.1mL) Equals 10 UK fluid ounces
1 metric cup (250mL) Equals 8.799 UK fluid ounces

| Cups (US) | Ounces (fluid) | Tablespoons (US) |
|---|---|---|
| 1 cup | 8 fl oz | 16 tbsp |
| 3/4 cup | 6 fl oz | 12 tbsp |
| 2/3 cup | 5.3 fl oz | 10.6 tbsp |
| 1/2 cup | 4 fl oz | 8 tbsp |
| 1/3 cup | 2.7 fl oz | 5.3 tbsp |
| 1/4 cup | 2 fl oz | 4 tbsp |
In order to make the translation process as simple as possible, one and a half cups is equal to twelve fluid ounces (US). However, it is important to keep in mind that this only applies to the measurement of liquids.
That fraction of a half is just the mathematical phrase for one multiplied by two. Use any calculator. Look at the answer you get if you divide 1 by 2. So 1.5 cups = 1 and 1/2 cups or 1 Plus 0.5 cups.
1 cup is equal to 4.5 ounces of dry weight (this measurement is used for dry substances like flour).
0.75 cups is equal to half of 1.5 cups.
