How many ounces in a liter? Can we live without ideology, concepts, and math?And the answer would be ‘NO BRAINER”


In our everyday life, measurement furnishes a quality and standard in daily routine things and processes. From weight to length and temperature to time even gravity is a measurement and it does play a very supreme role in our lives.

Thanks to these measurements’ existence in our whole world. And each passing day it is becoming more powerful and subtle inaccuracy. So that we can measure a tiny drop and even a vast Ocean.

how many ounces in a liter

So, today we will gain one more topic about measurement. Let’s experience it. Have you ever thought, “how many ounces are in a liter?”

Haven’t you?

The answer must be tricky!

As we might have worked with ML or liter and the Conversions are easier. Yet, this is different from fl oz.

Let’s understand what the FL OZ is!

What’s a Fluid Ounce?

In present, we have two types of Fluid Ounces, first is the U.S. Fluid Ounce was clarified around 1707 by Queen Anne and is based on a subdivision of the “Queen Anne Wine Gallon.” (The Queen Anne Wine Gallon is divided into exactly 128 fl oz) More routinely known today, just like, a U.S. Liquid Gallon.

Later The Imperial Fluid Ounce reformed by the British to standardize measures in the UK (United Kingdom) at the time, it was brought with the British Weights and Measures Act of 1824, known as The Imperial System of Weights and Measures. Said Fluid Ounce isn’t commonly utilised in the UK much these days because The metric measurement has is in charged.

Fluid Ounce

A FL ounce, abbreviated by the United States Customary & Imperial Systems of Measurement. It is a measure of volume,

One ounce is equal in value to 1/128 of a gallon, 1/32 of a quart, 1/16 of a pint and 1/8 of a cup.

What is Liter?

First Known Use of liter was in 1797. The word comes from French ‘ liter’, from Medieval Latin ‘litra’, a measure, from Greek, a weight. A liter is defined as a special name for a cubic decimeter.

One liter of liquid water has a volume of almost completely, one kilogram because the kilogram was initially defined in 1795 as the mass of one cubic decimeter of water at the temperature of melting ice (0 °C).

It is being utilized in both the measure system US & UK.

A liter is a measure of volume. It is equal to one cubic decimeter.

Liters are most commonly used for fluids and solids that can be poured. The liter is also used in some existed measurements, such as density (kilogram/Liter).

How many Ounces in a Liter of water?

How many Ounces are in a Liter of water?

1 Liter = 33.814 U.S. fl oz

1 Liter = 35.195 Imp. fl oz

So, in wind-up, the Imperial Fluid Ounce only weighs somewhat more than the U.S. Fluid Ounce as the Imperial Fluid Ounce is based on 10 pounds of Water, While the U.S. Fluid Ounce is defined as weighing exactly 8.345 pounds of Water.

Some more reference calculations from US ‘fl oz’ to ‘liter’

  • 8 fl oz = 0.2366 liter
  • 16 fl oz = 0.4732 liter
  • 24 fl oz = 0.7098 liter
  • 32 fl oz = 0.9464 liter
  • 64 fl oz = 1.8927 liter
  • 128 fl oz = 3.7854 liter

Let’s calculate it in math:

1 US gal = 3.7854 liters

1 US gal = 128 US fl oz

So, 1 US gal = 3.7854 liters

I think we had much discussed the technical thing. Now, we should go ahead with some practical stuff.

Let’s play

How many ounces are there in one and a half liter Milk-Jug? (The Jug is filled with Milk)

How many Ounces are in a Liter of water?

How to convert 1.5-L Milk to US fl oz?

The perfect amount to be calculated in liter(s) to the related value in US fl oz, we require to multiply the numbers in liter by 33.81 (as we already discussed it earlier).

Here we go:

X Fl oz = Y liter × 33.814 (fl oz US)

So, we have 1.5 liters Milk in the Jug and the calculation will be

1.5 L Milk x 33.814 US fl oz = 50.7210 US fl oz Milk

How many ounces are in a ten (10) cup coffee carafe? Convert value in liters.

How many ounces are in a ten (10) cup coffee carafe?

We need to follow some earlier lessons to solve this difficulty. So, first, do remember that A regular size cup is 8 US fl oz (though the coffee cup is 6 US fl oz size mostly)

But here we take the prescribed size of a cup. It’s 8 US fl oz in one cup. So, A 10 cups maker carafe would hold 80 US fl oz.

1 cup = 8 US fl oz

10 x 8= 80 US fl oz.

Now using the fl oz to liter conversation formula…

X Fl oz = Y liter × 33.814 (fl oz US)

X liter coffee = 2.36 L Coffee


  • The fl oz is a unit of Volume.
  • One is US fl oz and second Uk fl oz.
  • The Liter shows a Volume unit.
  • 1 Liter = 33.814 U.S. Fluid Ounces
  • 1 Liter = 35.195 Imperial Fluid Ounces
  • 1 US fl oz = 0.0296 Liter
  • 1 Imperial Fluid Ounces = 0.0284131 Liter
  • Gravity force or temperature of the atmosphere effects on weight but does not affect the Volume.

We don’t feel the need to remember the conversions as we are very much comfortable with their guessing by using cups and spoons than ounces and liters.

I hope you got the answer for “how many ounces in a liter?” Though at a professional level, we have to stay savvy in all these conversions.

So, it is very important to understand the value, perception, and importance in our everyday life.

Now, when you are making any dessert at home, don’t forget to measure in liters rather than cups.

Thank you 😊
