Liters to Ounces Conversion Guide and Calculator

Converting Liters to Ounces: A Guide to Fluid Measurements

When following recipes, mixing drinks, or tracking your fluid intake, you may need to convert between metric and imperial units. Understanding how to translate liters (L) to fluid ounces (oz) allows you to quickly calculate amounts for your needs.

In this guide, we’ll cover:

• How many ounces are in a liter
• Converting liters to fluid ounces step-by-step
• Real-world examples like converting 2.2 liters to ounces
• How to go from fluid ounces back to liters
• Handy conversion charts for reference

Let’s explore the relationship between these common units of liquid measurement!

Defining Liters and Ounces

First, a quick refresher on what these units represent:

• A liter is a metric unit equal to 1,000 milliliters (mL) or 1 cubic decimeter.
• A fluid ounce is an imperial unit of volume equal to 1/128 of a gallon or about 29.57 mL.

With liters being a much larger base unit, it takes multiple fluid ounces to equal one liter. But the exact conversion depends on whether we are talking about US or Imperial fluid ounces.

US Fluid Ounces

One liter is equivalent to 33.814 US fluid ounces. To be more precise, one liter equals:

• 33 fluid ounces
• Plus 0.814 fluid ounces

This strange conversion exists because US fluid ounces (about 29.57 mL) are slightly smaller than Imperial fluid ounces (about 28.41 mL).

Imperial Fluid Ounces

When converting to Imperial fluid ounces, one liter is equal to 35.195 fluid ounces. Specifically:

• 35 fluid ounces
• Plus 0.195 fluid ounces

This is because Imperial fluid ounces have a slightly smaller volume than US fluid ounces.

Converting Liters to US Fluid Ounces

Now that we know 1 liter equals 33.814 US oz, let’s walk through some examples converting liters to US fluid ounces:

Converting Whole Liters

To start, converting whole liters to whole fluid ounces is straightforward. Since 1 L = 33.814 oz:

• 2 liters x 33.814 oz/L = 67.628 oz
• 3 liters x 33.814 oz/L = 101.442 oz
• 5 liters x 33.814 oz/L = 169.07 oz

So for whole liter values, simply multiply by 33.814 and round to the nearest ounce.

Converting Decimals

For decimal values, multiply the decimal portion by 33.814 separately. For example:

• 1.5 L x 33.814 oz/L = 50.721 oz
• 2.4 L x 33.814 oz/L = 81.154 oz

Converting 2.2 Liters to Ounces

Let's look at converting 2.2 liters specifically:

• 2 liters = 2 x 33.814 oz = 67.628 oz
• 0.2 liters = 0.2 x 33.814 oz = 6.763 oz
• Total = 67.628 + 6.763 = 74.391 oz

So 2.2 liters converts to 74.391 US fluid ounces when rounded to 3 decimal places.

Converting Imperial Liters to Fluid Ounces

The steps for converting Imperial liters to fluid ounces are the same, just using 35.195 oz per liter instead of 33.814 oz.

For example:

• 2 L x 35.195 oz/L = 70.39 oz
• 3 L x 35.195 oz/L = 105.585 oz

To convert 2.2 Imperial liters:

• 2 L = 70.39 oz
• 0.2 L = 0.2 x 35.195 = 7.039 oz
• Total = 70.39 + 7.039 = 77.429 oz

Converting Ounces Back to Liters

To go from fluid ounces back to liters, simply divide by the conversion factor:

• US oz to liters: divide by 33.814
• Imperial oz to liters: divide by 35.195

For example:

• 50 oz / 33.814 oz/L = 1.478 L
• 80 oz / 35.195 oz/L = 2.274 L

Handy Liters to Ounces Conversion Chart

For easy reference, here is a conversion chart for common liter and fluid ounce values:

Liters	US Fluid Ounces	Imperial Fluid Ounces
1 L	33.814 oz	35.195 oz
2 L	67.628 oz	70.39 oz
3 L	101.442 oz	105.585 oz

Converting Milliliters to Ounces

The same principles apply when converting milliliters (mL) to ounces:

• 1 mL = 0.033814 US oz
• 1 mL = 0.035195 Imperial oz

Some examples:

• 500 mL = 500 x 0.033814 = 16.907 oz
• 250 mL = 250 x 0.035195 = 8.799 oz

When Converting Liters and Ounces Matters

Here are some situations where converting between liters and fluid ounces is useful:

• Following recipes - Convert fluid measurements in cookbooks or online
• Calculating hydration - Monitor daily water intake goals
• Mixing drinks - Convert cocktail recipes between units
• Portioning food or drink - Measure out precise serving sizes
• Comparing containers - Assess different bottle, jug, or reservoir volumes

The Takeaway

Converting fluid volumes between liter and ounces is straightforward once you know the conversion factors. Common ones to remember are:

• 1 liter = 33.814 US fluid ounces
• 1 liter = 35.195 Imperial fluid ounces

Use these to convert decimal values in liters to ounces. Just multiply the number of liters by the conversion factor. Going from ounces back to liters is done by dividing by the same conversion factor.

With this knowledge, you can easily translate liters to ounces whether following recipes, monitoring your hydration, or any application that involves measuring liquid volumes.
