US vs. Imperial Ounces: A Critical Distinction
One of the most common points of confusion arises from the existence of two different types of fluid ounces: the US fluid ounce and the Imperial fluid ounce, which is used in the UK. These are not the same, and using the wrong one can lead to inaccurate results, especially in recipes. The Imperial fluid ounce is slightly smaller than the US version.

This means the conversion for 500ml differs depending on which system you are using. To convert 500ml to imperial ounces, you would divide 500 by 28.4131, which gives you approximately 17.60 imperial fluid ounces.
