How Many Ounces in a Liter

How Many Ounces in a Liter

According to The Calculator Site, ounces to liters must be one of the trickiest conversions in units of measurement because you first need to convert liters to millilitres before you get to arrive at ounces.

Regardless, they are also two of the most important units of measurement for volume because both of them are commonly used not only in cooking but also in serving sizes for liquid ingredients in the supermarket. As such, it is also very essential to know how many ounces are in a liter.

What is liter?

Liter is commonly found in almost all beverages that are sold in large volumes. Expressed by the abbreviation L. In unit conversions, 1 liter is equivalent to 1000 mL or 1 US quart. It is said that one jug of water is exactly equivalent to one liter.

1 liter = 1000 ml = 1 US quart

It is also considered as the most used unit to measure liquids and is also applicable for any dry or solid ingredients which are poured.

Are US and UK litres the same?

According to The Good Kitchen, US and UK litres are the same. This is quite important to know for two reasons. First, the similarity between US and UK litres make it the only similarity they have in terms of unit conversions. For all other units of measurement, the UK and US metric system are considered as their variants.

This leads us to the second importance of this similarity. This means that while there is ease in converting liters to liters, there will be much effort in converting UK and US liters using other units of measurement. For example, when converting UK liter to UK gallon, we need to multiply it with 1.2 in contrast with the US gallon of 1.

How many ounces in a liter

The first thing to acknowledge here is the fact that ounce is different from fluid ounces. Fluid ounces measure volume and ounce measure weight. Unfortunately, there is no exact conversion to ounce because converters always assume that since you are looking for liters, what you are measuring are liquid ingredients.

Because of this, converters make use of the US fluid ounce conversion value of 33.81. Although there is no available liter to ounce conversion, there is an available ounce to liter and we know, according to The Kitchen, that its value is 1 ounce is equivalent to 0.02957 US liters or 29.57 mL and 0.02841 to UK/imperial liters.

1 ounce = 0.02957 US liters

1 ounce = 0.02841 imperial liters

How many US fluid ounce in a liter?

We have answered this a bit from the previous section. For the conversion of liters to fluid ounces using the US fluid ounce, we will use the conversion value of 33.81.

1 liter = 33.81 US fluid ounce

How many imperial fluid ounce in a liter?

We all know that there is a slight difference between the US and UK fluid ounce. If you need to convert liters through the imperial fluid ounce, you need to use the conversion value of 35.19.

1 liter = 35.19 UK/imperial fluid ounce

How many fluid ounces in a liter?

Well, base from the two previous sections, we know that the answer to this is not one but two. We already stated that fluid ounces to liters can either be expressed using the US conversion value or the UK or imperial conversion value.

We have also mentioned that for you to be able to do this, you must know that there are 33.81 US fluid ounces in a US liter and 35.19 UK fluid ounces in one UK liter.

1 liter = 33.81 US fluid ounces

1 liter = 35.19 imperial fluid ounces

How many ounces in 2 liters

So here, we are talking about ounces and not fluid ounce. We have previously mentioned that there is no direct conversion between liter to ounce so we must first express the 2 liter given to mL and divide it with the conversion value of either the US or imperial type.

Since 1 liter is equal to 1,000 mL, we know that we have to divide 2,000 mL to either 29.57 for the US ounces or 28.41 for the imperial ounces. Thus, if you need the US ounces, there are 67.63 US ounces in 2 US liters while there are 70.39 imperial ounces in 2 UK/imperial liters.

2 liters = 67.63 US ounces

2 liters = 70.39 imperial ounces

How many ounces in 1.5 liters

Following the previous computation, we need to express 1.5 L again to mL. From this, we will get a value of 1,500 mL. You can generate two answers here since we are converting to either the US or imperial ounce.

Thus, there are 50.72 US ounces in 1.5 US liters (from 1,500 divided to the US ounce conversion value of 29.57) and there are 52.79 imperial ounces in 1.5 imperial liters (from 1,500 divided to UK/imperial conversion value of 28.41.)

1.5 liters = 50.72 US ounces

1.5 liters = 52.79 imperial ounces

How many 8 ounce glasses are in a liter?

According to this site called Calculate Me, there are 6.7628 glasses in one liter if we get the accurate measurement of the typical glass and convert it to liter. But since we are talking specifically of 8 ounce glasses here, there would be four 8 ounce glasses in one liter.

1 liter = 4 8-ounce glasses

Is 4 liters of water a day too much?

Health and fitness sites would tell us that we need to drink eight full glasses of 8 ounce glasses per day to stay dehydrated and for our body to achieve its homeostasis. This is called the 8×8 rule for every day water intake. If we follow this rule and convert it to liters, then we need two liters of water daily for our bodies to stay hydrated.

According to Health Line, four liters of water may or may not be too much because it depends on your geographical location. According to an article in the site, people who come from humid, and hotter climates may exceed their 2 liter intake to 4 or even 5 depending on the need.

However, for people who live sedentary lives or are from colder climates, they have to at least meet the two liter prescribed water intake daily to keep the body homeostasis.

Liters to ounces conversion table

For this section, it would be more practical to present liters to fluid ounces because both units of measurement are confined within measurements of liquid volumes. We will divide the conversion tables between the US and UK/imperial conversions.

US LitersUS Fluid Ounces
UK/Imperial LitersUK/Imperial Fluid Ounces


Drawing from what were illustrated in the previous sections, we can conclude that the question on how many ounces are in a liter is quite important because both they are two of the most commonly used units of measurement for weight and volume, respectively.

However, we must be very clear that there are no exact conversions for liters to ounces and that the common reference to ounces would be in terms of fluid ounces. It is also highlighted that although the UK and US liters are the same, they will become very different once they are converted to other units of measurements because we are following either the UK or imperial and US conversion values.
