Want to convert 2 liters to oz? It can be confusing figuring out how many ounces are in 2 liters, especially for fluid ounces. Fear not, as we’re covering every possible conversion you may need!

The reason this is a confusing conversion? Ounces are strictly speaking a weight measurement (think 16 ounces in a pound). However, ounces also refer informally to the volume measurement fluid ounces (think 32 fluid ounces in a quart). 

So what happens when you’re following a metric recipe calling for 2 liters of something? Well, you might find yourself using a half gallon, quart or even water glasses for measuring purposes. 

That means converting 2 liters to oz or knowing how many ounces are in 2 liters. Read on to learn more!

How Many Ounces In 2 Liters (for Fluid Ounces)

To get started, 2 liters always equals 2000 milliliters (mL). However, not all fluid ounces are the same:

• One US Customary (USCS) fluid ounce is 29.57 mL or 1/16 US pint. This is the system used in most US recipes.
• One US Legal fluid ounce is 30.00 mL. This is the system used on US food and beverage packaging.
• One UK Imperial fluid ounce is 28.41 mL. This is seldom used but may appear in older British recipes.

Consequently, the 2 liters to oz conversions are as follows:

• There are 67.63 US Customary fluid ounces in 2 liters.
• There are 66.67 US Legal fluid ounces in 2 liters.
• There are 70.40 UK Imperial fluid ounces in 2 liters. 

These conversions apply to all liquids, whether you’re measuring soda, milk, water or honey even. 

Measuring 2 Liters using Ounces

Unfortunately, measuring 2 liters using fluid ounces is not the easiest. The USCS measurement of 67.63 fl oz is most closely approximated as:

• 2.1 quarts (67.2 fl oz), or
• 4 ¼ pints (68 fl oz), or 
• Half a gallon (64 fl oz)

While the half gallon approximation is most well-known, it is still 5% less than 2 liters. To correct it, add 7 tablespoons or 3 ½ fluid ounces to the half gallon to make the full 2 liters.

How Many Oz In 2 Liters (by Weight)

While fluid ounces measure volume, you may also be wondering about ounces by weight (avoirdupois). For example, 2 liters of cold water weighs 2000 grams or 70.55 ounces on a kitchen scale.

Since every substance has a different density, there is a different conversion between volume in liters and weight in ounces. The following table shows conversions for common ingredients:

Volume	Weight
2 liters water	70.5 ounces
2 liters milk	70.5 ounces
2 liters of cream	71.5 ounces
2 liters honey	101 ounces
2 liters granulated sugar	60 ounces
2 liters dry rice	55 ounces

While these conversions are provided for convenience, note that liters to ounces usually refers to fluid ounces of volume, not weight.

FAQ

Is 64 oz of water 2 liters?

No, 64 fluid ounces is not 2 liters, but only a rough approximation of it. In US Customary measurements, there are actually 67.6 fl oz in 2 liters. In US Legal measurements, there are 66.7 fl oz in 2 liters. 

Is 2 liters half a gallon?

A half gallon is only a rough approximation for 2 liters. Half of a US gallon equals 64 fluid ounces, whereas 2 liters is 67.6 fluid ounces. Therefore, a half gallon is about 5% less than 2 liters and should be topped up with an additional 3 ½ fl oz in order to make 2 liters.

How many 8 oz glasses in 2 liters?

There are approximately eight 8-oz glasses in 2 liters. Note that eight 8-oz glasses equals 1.92 liters, about 4% less than the full 2 liters. You need to add about 7 tablespoons of liquid to top up to 2 liters, although it’s generally better to use measuring cups for the most accurate measurements.
