What is Half of a 3/4 Cup?

Cups are often used as a measure of volume and even weight - if the volume is known and one knows density, it is fairly easy to calculate the weight of the ingredients in the cup.

However, although the size of the cup is more or less standardized, it may sometimes be hard to find the actual volume or mass of content that is given in fractions of a cup. For example, many readers want to know what is half of a 3/4 cup ...

Size of the Cup

There are two standard sizes for of the cup:

1 US Legal Cup = 8.11537 US Fluid Ounces = 0.24 liters = 240 milliliters

1 Imp Cup = 10 Imp Fluid Ounces = 0.284131 liters = 284.131 milliliters

Thus, we can write:

1 US Legal Cup = 0.844682 Imp Cup

or,

1 Imp Cup = 1.18388 US Cup

However, very rarely will somebody convert US cups to Imperial cups and vice versa.

Note: If You have a recipe that uses cups as a means of volume/weight measure, don't worry if your cups are standard size cups (they are probably not), just always use the same cup when measuring the ingredients - in recipes the amounts are important, but much more important are ingredients' ratios.

Now that we know how much is a cup, we can also write:

3/4 US Cup = 6.0865275 US Fluid Ounces = 0.18 liters = 180 milliliters

3/4 Imp Cup = 7.5 Imp Fluid Ounces = 0.21309825 liters = 213.09825 milliliters

thus, if we want to know how much is half of a 3/4 cup, then:

(3/4 Cup) / 2 = 3/8 Cup

3/8 US Cup = 3.04326375 US Fluid Ounces = 0.09 liters = 90 milliliters

3/8 Imp Cup = 3.75 Imp Fluid Ounces = 0.106549125 liters = 106.549125 milliliters

So, if You want to know what is half of a 3/4 cup, the answer is 3/8 cup.
