However, it's important to note that this is a conversion between the US customary system and the metric system. There are two types of ounces used in the US:

* Fluid ounces (fl oz): These are used to measure volume, and 1 liter is equal to 33.814 fluid ounces.

* Avoirdupois ounces (oz): These are used to measure weight, and are not relevant to volume measurements.
