How Many Ounces Are in a Liter?

Multiply the volume by 33.8141

1 Liter ≈ 33.8141 U.S. Fluid Ounces

In the UK, a litre is equivalent to 35.195 imperial fluid ounces. This difference arises because the US fluid ounce is slightly larger than the imperial fluid ounce. Specifically, one US fluid ounce equals 29.5735 milliliters, whereas one imperial fluid ounce equals 28.4131 milliliters.

What is Volume?

Volume is the amount of space consumed by a three-dimensional object, liquid, or gas. Volume is often measured using cubic units of length, such as the cubic inch, or specially named units such as the gallon.

Fluid Volume

Fluid volume is the amount of three-dimensional space consumed by a fluid substance. Fluid volume measurements are commonly used in construction, cooking & baking, science, and math.

US customary volume measures include fluid ounces, cups, pints, quarts, and gallons. Internationally, fluid volume is measured using liters, milliliters, imperial gallons, imperial quarts, and imperial pints.

How to Calculate Volume

The volume of a regular shaped object can be calculated by measuring the sides of the object and applying a mathematical formula. If you're trying to calculate volume, check out our volume calculator to calculate several shapes. Finding the volume enclosed in an irregular shape can be more difficult. One method for finding the volume of an irregular shape is to use a technique called displacement. Using displacement, an object is placed in a container of liquid and the amount of liquid displaced is measured, this is the volume of the object.

How to Convert Units of Volume

There are two steps to convert a unit of volume to a different unit. First, you'll need to find the conversion ratio, which is the rate of one unit to another. Check out the conversion tables below for a complete list of conversion ratios. Once you've found the conversion ratio, multiply the value you want to convert by the conversion ratio.
