What is a Cup? 

A cup is a unit of volume used mainly in the United States. However, the definition of a cup may vary depending on where you live.

The two main cup measurements are the US cup and the UK cup, and they are not the same:

  • US cup. In the United States, 1 US cup roughly equals about 240 milliliters (ml) or 8 fluid ounces (fl. oz.). This is the standard in American recipes and cookbooks.
  • UK cup. In the United Kingdom, 1 UK cup is slightly bigger, approximately 284 milliliters (ml) or 10 fluid ounces (fl. oz.). This distinction becomes pertinent when working with UK recipes or converting between US and UK measurements.

What is Half of 1/3 Cup?

Here is how to work out what 1/3 of a cup is:

Step 1: Establish the measurement of 1/3 cup.

  • Begin with 1 cup, which equates to 240 milliliters (ml) in the US or 284 milliliters (ml) in the UK.
    • For the US Cup:
      • 1/3 cup amounts to 1/3 of 240 ml, yielding 80 ml.
    • For the UK Cup:
      • 1/3 cup translates to 1/3 of 284 ml, approximating 94.67 ml (rounded).

Step 2: Calculate half (50%) of 1/3 cup.

  • For the US measurement:
    • Half of 1/3 cup constitutes 50% of 80 ml, equaling 40 ml.
  • For the UK measurement:
    • Half of 1/3 cup constitutes 50% of approximately 94.67 ml (rounded), resulting in approximately 47.33 ml (rounded).

So, half of 1/3 cup is equal to about 40 ml in the US or roughly 47.33 ml in the UK. 

To measure it precisely:

  • Use a liquid measuring cup to the appropriate level based on the desired measurement (40 ml for the US or 47.33 ml for the UK).
  • Suppose you do not have a liquid measuring cup with the exact measurement. In that case, you can utilize a 1/4 cup measuring cup and measure a portion of it (since 1/4 cup is 60 ml in the US) or employ a similar method for the UK using a rounded 1/4 cup (given that 1/4 cup approximates 71 ml in the UK).
