It's important to note that this is an approximation because there are actually two different types of fluid ounces:

* US fluid ounces: This is the most common type used in the United States.

* Imperial fluid ounces: This type is used in the United Kingdom, Canada, and other Commonwealth countries.

The conversion factor above is for US fluid ounces.

If you need the conversion for Imperial fluid ounces, there are approximately 35.19 Imperial fluid ounces in a liter.
