Converting From Cups To Ounces

Converting From Cups To Ounces

If you have a recipe featuring measurements in cups then it’s likely to be one of two things:

  1. A US recipe (using the US customary cup)
  2. An old (pre-1970s) UK recipe (using the imperial cup)

If it’s a recipe from anywhere else in the world or a more recent UK recipe, then it’ll likely be referencing the international metric cup. And then there’s the ounce, which comes as a dry ounce or fluid ounce. For this discussion, we’ll focus on the fluid ounce. Should you wish to convert using the dry ounce then give our cups to ounces converter a try.

The fluid ounce has two different measurements – there’s the US fluid ounce and the UK fluid ounce. It can get complicated, especially if you’re using a US recipe and based in the UK, or vice-versa. But, fear not, for I will break it down for you. Let’s look at the conversions of each:

US recipes – cups to ounces

  • 1 US cup (236.59mL) = 8 US fluid ounces
  • 1 US cup (236.59mL) = 8.327 UK fluid ounces

Old UK recipes – cups to ounces

  • 1 UK cup (284.13mL) = 10 UK fluid ounces
  • 1 UK cup (284.13mL) = 9.607 US fluid ounces

Rest of the world recipes

  • 1 international metric cup (250mL) = 8.454 US fluid ounces
  • 1 international metric cup (250mL) = 8.799 UK fluid ounces

Cups to an ounces conversion table

I’ve included two quick-reference tables of conversions to help you see how many fluid ounces there are in a cup. The first uses the standard US customary cup (236.59mL) and the second uses the UK imperial cup (284.13mL).
