How to Convert Fluid Ounces to Liters
To convert fluid ounces to liters, multiply the volume by the following conversion ratio: 0.0295735 liters/fluid ounce.
Since one fluid ounce is equal to 0.0295735 liters, you can use this simple formula to convert:
The volume in liters is equal to the volume in fluid ounces multiplied by 0.0295735.
For example, here's how to convert 32 fluid ounces to liters using the formula above.
How Many Liters Are in a Fluid Ounce?
There are 0.0295735 liters in a fluid ounce, which is why we use this value in the formula above.
Our fluid ounce to liter calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Fluid Ounces and liters are both units used to measure volume. Keep reading to learn more about each unit.
What Is a Fluid Ounce?
A fluid ounce is a unit of volume equal to 0.0295735 liters (L), the base unit for volume. 1/128 of a US gallon (29.5735 mL). [1]
The fluid ounce is classified as a US customary unit of volume. Fluid Ounces can be abbreviated as fl oz; for example, 1 fluid ounce can be written as 1 fl oz.
When working with fluid ounces (fl oz) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, fluid ounces (fl oz) are widely used across standard volume applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Liter?
Metric unit of volume equal to 1 cubic decimeter (1,000 mL). It serves as a primary reference unit for measuring volume across scientific and practical applications. [2]
The liter is classified as a metric and SI-compatible unit of volume. Liters can be abbreviated as L; for example, 1 liter can be written as 1 L.
As the primary coherent reference unit for volume in this category, all other volume units are mathematically anchored to the liter (L).
In practice, liters (L) are widely used across standard volume applications within SI metric workflows, engineering documentation, and technical data sheets.
When converting volume between fluid ounces (fl oz) and liters (L), keep full floating-point precision (1 fl oz = 0.0295735 L; 1 L = 33.8140227 fl oz) during intermediate calculations and round only the final liter figure to match your instrument tolerance.
