There are two types of ounces that people use when measuring liquids:

* Fluid ounces (fl oz): This is the most common type in the US.

* Imperial ounces (imp oz): This is the most common type in the UK and other countries using the imperial system.

Here's how to convert liters to ounces:

* Liters to Fluid Ounces (US): 1 liter = 33.814 fluid ounces (fl oz)

Therefore, 2 liters = 2 * 33.814 = 67.628 fluid ounces (fl oz)

* Liters to Imperial Ounces (UK): 1 liter = 35.195 imperial ounces (imp oz)

Therefore, 2 liters = 2 * 35.195 = 70.39 imperial ounces (imp oz)

So, depending on the type of ounce you're looking for, 2 liters is equal to either 67.628 fluid ounces or 70.39 imperial ounces.
