When to use this converter

Helpful for labeling home-cooked portions or cocktail recipes where cup measurements need to match fl oz.

Common mistakes to avoid

  • 1 US cup = 8 fl oz exactly. A metric cup (250 mL) = 8.45 fl oz.
  • Weight ounces and fluid ounces are different; this converter is for volume only.
Quick example 2 cups of broth = 16 fl oz. Matches a standard pint bottle.
