How many Ounces in a Cup?

The most common question in cooking is: How many Ounces in a Cup? Unfortunately, the answer to this question is not as simple as you think. But I will help you to make it simple and easy to understand. Just keep reading the post. So, let’s start.

Basically, there are three types of measurement in ounces.

  1. US Fluid Ounces
  2. UK Fluid Ounces
  3. Rest Countries Fluid Ounces

Firstly, it looks confusing. Right? Especially when you are following a UK recipe and lived in the US, or reverse. But, don’t worry I will break your confusion. So, first, let’s jump to the conversion.

How many Ounces in a Cup?

Liquid measuring cups define this question’s answer. Also, you can find the difference of US, UK, and other region measurement values.

1) As per US Recipe

1 US customary cup = 8 US fluid ounces
1 US customary cup = 8.327 UK fluid ounces

Note: 1 US cup = 236.59 mL

It means 1 US cup of liquid is equal to 8 US fluid ounces. Similarly, 1 US cup is equal to 8.327 UK fluid ounces.

In other words, it only works for US recipes. So, when you are following US recipe in the UK, then you have to count 8.327 fluid ounces.

Although in UK recipes it measures like below.

2) As per UK Recipe

1 UK imperial cup = 10 UK fluid ounces
1 UK imperial cup = 9.607 US fluid ounces

Note: 1 UK cup = 284.13 mL

3) Rest Countries

1 international cup = 8.454 US fluid oz
1 international cup = 8.799 UK fluid oz

Note: 1 international cup = 250 mL

So, if you are following recipes from other countries then you can take an international cup as a reference. Also, you can see the measurement is different for the US, UK, and other regions.
