Have you ever wondered how many cups of water make a liter?
If you are baking, cooking, or doing a science experiment that uses liters, but your measuring cups only measure cups, you have discovered the conflict between the Imperial Measurement System and the Metric Measurement System.
The most common confusion in these conversions occurs when Americans use recipes or instructions from other countries.
So, how many cups of water make a liter? On average approximately 4.23 cups of water make a liter of water:
- 1 Liter = 4.2267528377 US cups
- 1 Liter = 3.5195 Imperial cups
- 1 Liter= 4 Metric cups
- 1 Liter= 4.399384966 Canadian cups
How Many Cups of Water Make a Liter?
There are approximately 4.23 cups of water in a liter. Cups use the Imperial Measurement system, and Liters use the Metric Measurement system.
That is why the conversion is not in whole numbers. This also means that one cup is approximately 0.2366 Liters.
Liters to Cups Conversion:
- 1/8 liter = 0.52 cup
- 1/4 liter = 1.05 cup
- 1/2 liter = 2.11 cups
- 1 liter = 4.22 cups
- 1.5 liters = 6.34 cups
- 2 liters = 8.45 cups
- 2.5 liters = 10.56 cups
The table below shows the common conversion from liters to cups:
History of the Metric Measurement System
The Metric System traces its origins to the late 18th century in France. Gabriel Mouton presented the system in the late 17th century, and after 100 years of development, the French government adopted the system.
The intention of adopting the system was to create a unified system of measurement. The metric system is decimal-based.
The meter (the base measurement of distance in the metric system) was based on being a portion of the Earth’s circumference.
This basis of Earth’s circumference has made the Metric System incredibly useful for scientific studies.

History of the Imperial Measurement System
The Imperial Measurement System is also known as the British Imperial System. The British Imperial System traces its origins back to the middle ages.
During this time, however, there was not much consistency in what qualified as a foot, a gallon, or a pound. Many of these measurements were based on agricultural measurements, which could vary.
Common measurements adopted throughout time to define a foot include “the length of the left feet of 16 men lined up heel to toe as they emerged from church” and “containing 12 inches, each inch equaling the length of three barleycorns.”
In the 19th century, the British government standardized the measurements for the Imperial Measurement System.
At the same time, the United States was adopting their standard version of the British Imperial System, which slightly varied, depending on what they used to define the standard units of a gallon, a foot, and a pound.
Now the system the United States uses is regularly called the Imperial System. It is also known as the United States Customary System.
Why Does the United States Not Use the Metric System?
The United States used the Imperial System during its industrial revolution. This meant all of the factories and factory workers were designed and trained, respectively, with the Imperial System in mind.
In the past, when the United States government has attempted to convert to the Metric System, companies and consumers have blocked the passage.
Companies do not want to convert all of their equipment over to the Metric System, as this process would be lengthy and expensive.
Consumers trained in the Imperial System do not want to learn the Metric System.
What Other Places Use the Imperial Measurement System?
Most countries in the world have adopted the Metric System of measurements. The only countries that still use the Imperial Measurement System are the United States of America, Liberia, and Myanmar.
What Units do Baking Recipes Use in the Different Systems?
The metric system does most of its measurements by weight or volume. Measurements will be primarily in milliliters (mL) or grams (g). Most Metric recipes will call for temperatures in Celsius (C).
The Imperial system uses different measurements for weight or volume. Most Imperial recipes will call for teaspoons (t), tablespoons (T), cups (c.), and ounces (oz) or pounds (lbs).
Celsius vs. Fahrenheit
Celsius is the primary unit for measuring temperature in the Metric System. In the Metric System, water freezes at 0 degrees Celsius, and water boils at 100 degrees Celsius.
Fahrenheit is the primary unit for measuring temperature in the Imperial System. In the Imperial System, water freezes at 32 degrees Fahrenheit and water boils at 212 degrees Fahrenheit.
Fluid ounces measure the capacity of liquids. Ounces are based on being a fraction of a pint. In the British Imperial System, fluid ounces are slightly different than in the American Imperial System.
Fluid ounces in the United States are measured as one-sixteenth of a US pint. This makes about 29.57 mL (to use the Metric System equivalent).
Fluid ounces in the British Imperial System are equal to one-twentieth of a British pint. This makes a British fluid ounce around 28.41 mL.
British Pints vs. American Pints
Part of the difference between fluid ounces in the United States versus fluid ounces in the United Kingdom is based on the difference in how pints are measured.
In the British Imperial System, a “pint” is about 568 milliliters. This equates to around 20 US fluid ounces. In the United States, a “pint” is about 473 milliliters.
This measures in around 16 US fluid ounces.
Since a cup is defined as one-half of a pint, “cup” measurements may also vary between the two systems.
That is why most Metric System recipes will call for measurements in milliliters rather than ounces, cups, or pints.
Other Important Conversions
How Many Cups of Water Make a Quart?
There are four cups of water in one quart. A quart is a unit in the Imperial Measurement System.
How Many Ounces Are in a Pound?
There are 16 ounces in a pound. The Imperial Measurement System uses both ounces and pounds.
How Many Grams Are in an Ounce?
There are about 28.35 grams in an ounce. Grams are generally used in the Metric System, and ounces are traditionally used in the Imperial System.
How Many Liters Are in a Gallon?
There are about 3.79 liters in a gallon. Gallons are used in the Imperial System, and liters are used in the Metric System.
Making Conversions on Your Own
Converting between the Imperial Measurement System and the Metric Measurement System will take math, but it is not impossible.
Simply find the rate of conversion between the two, multiply the value you are given in one, and you will have the weight you need in the other.
For example, one tablespoon is approximately 14.787 milliliters. This can also be shown as one tablespoon/14.787 milliliters. Therefore, the rate of conversion is 14.787.
If you are given three tablespoons in a recipe, and you want to convert to milliliters, simply multiply by 14.787. You will need 44.36 milliliters to obtain the correct amount.
Many of these conversions are also easily searchable through websites that will do the math for you if you do not want to include a calculator in your cooking.
What If You Do Not Want to Convert?
If you do not want to do the conversions on your own, there are easy workarounds. You can buy a set of measuring cups and spoons in Imperial measurements if your cookbooks are from the US.
If you live in the United States and regularly want to use recipes from other countries, investing in a kitchen scale can save you tons of hassle.
Some cookbooks, like Crazy Sweet Creations by Ann Reardon, also offer recipes in both Imperial and Metric measurements.
If you use that book, no matter where you live or what measurements you use, you can have fun in the kitchen.
