Liters to Ounces Converter

What is a liters to ounces converter?

A liters to ounces converter turns a metric volume in liters (L) into US fluid ounces (fl oz), the unit most often used in American recipes and on US packaging. Because the two systems describe the same physical volume, the conversion is exact once you know how many milliliters make up a single fluid ounce. This tool runs the conversion in both directions, so you can also go from fluid ounces back to liters.

Formula

One US fluid ounce equals 29.5735 milliliters, and one liter equals 1000 milliliters. The conversion factor is therefore:

$\text{fl oz} = \text{liters} \times \frac{1000}{29.5735} = \text{liters} \times 33.814023$

To go the other way:

$\text{liters} = \frac{\text{fl oz}}{33.814023} = \text{fl oz} \times 0.0295735$

How to convert liters to ounces

1. Take your volume in liters.
2. Multiply it by the base factor: 1 liter = 33.814023 US fluid ounces.
3. The result is the equivalent volume in US fluid ounces.

For the reverse, divide the number of fluid ounces by 33.814023 (or multiply by 0.0295735) to get liters.

Worked examples

1 liter to fluid ounces

$1 \times 33.814023 = 33.814023 \text{ fl oz}$

So 1 liter is about 33.81 US fluid ounces.

10 fluid ounces to liters

$\frac{10}{33.814023} = 0.295735 \text{ L}$

So 10 US fluid ounces is about 0.2957 liters.

2 liters to fluid ounces

$2 \times 33.814023 = 67.628046 \text{ fl oz}$

So 2 liters is roughly 67.63 US fluid ounces.

FAQ

Are these US or UK fluid ounces?

This converter uses US fluid ounces, where 1 fl oz = 29.5735 mL. A UK (imperial) fluid ounce is slightly smaller at 28.4131 mL, so the numbers differ if you are working with imperial measurements.

How many fluid ounces are in a liter?

There are about 33.814 US fluid ounces in one liter. For a quick mental estimate, a liter is just under 34 fluid ounces.
