The ounce is a mass or weight unit, whereas the litre is a volume unit. As a result, without knowing the density of the substance in question, you cannot directly convert ounce to litre.

If you know the density of the substance, you can convert ounce to liter using the following formula:

Volume (in litres) = mass (in ounces) divided by density (in ounces per liter)

For example, if you have 16 ounces of water with a density of 1 ounce per millilitre, you can convert it to litres using the formula:

16 ounces of mass
1 ounce per millilitre = 0.001 ounces per litre density

volume = mass / density = 16 / 0.001 = 16,000 mL = 16 L

As a result, 16 ounces of water equals 16 litres. However, if you are dealing with a different density substance, the conversion factor will be different, as will the resulting volume in litres.
