Convert Volume from Quarts to Liters (qt to l)

Quart to Liter Conversion Formula

Example

Let's convert 5 Quart (qt) to Liter (l).

Using the formula:

Therefore, 5 Quart (qt) is equal to 4.731764744251398235 Liter (l).

How many quarts are in one liter? One Liter (l) contains 1.05668820625 Quarts (qt) — the inverse of the factor above. Multiplying by 0.946352948850279647 takes you from quarts to liters; multiplying by 1.05668820625 brings you back.

Put in words: one quart equals 0.946352948850279647 liters, so the quart is the smaller unit of this pair. Converting between them never changes the amount of volume being measured — only the size of the unit you count it in.

What is a Quart (qt)?

A quart (qt) is a unit of volume measurement.

A single quart is equal to 32 fluid ounces (fl oz), 2 pints, or 4 cups.

It is a key measurement in both the imperial and United States customary systems. The plural form is quarts.

Where Does the Name "Quart" Come From?

The word "quart" comes from the Latin word quartus, meaning "a fourth part."

This name is a direct clue to its size: a quart is exactly one-quarter of a gallon. This simple relationship makes it an easy-to-remember unit.

US vs. Imperial (UK) Quarts: A Key Difference

It's crucial to know that the US and Imperial (UK) quarts are not the same size. While both systems are related, their definitions for a quart differ significantly.

• A US liquid quart is equal to approximately 946.35 milliliters.
• An Imperial quart (UK) is about 20% larger, equal to approximately 1,136.52 milliliters.

This difference is critical to remember when converting recipes or measurements between countries.

What's the Difference Between a Liquid and a Dry Quart?

The United States customary system also distinguishes between a liquid quart and a dry quart.

A liquid quart is used for liquids like milk or oil, while a dry quart measures the volume of dry goods like berries or flour.

They are not the same volume.

• A US liquid quart is about 0.946 liters.
• A US dry quart is slightly larger, equaling approximately 1.101 liters.

What is a Liter (l)?

A liter (l) is a fundamental unit used to measure volume in the metric system.

In simple terms, it measures the amount of space a substance occupies, like the amount of soda in a bottle. The plural form is liters.

Where Did the Liter Come From?

The liter was introduced in France in 1795 during the French Revolution.

It was created as part of a movement toward a more logical and universal system of measurement, which later evolved into the modern metric system.

Initially, the definition of a liter was based on the weight of one kilogram of pure water.

How Is a Liter Defined Today?

While the original definition was based on the mass of water, it was updated for greater precision and consistency.

Today, the official definition directly connects the liter to a unit of length, making it easier to understand.

So, how big is a liter?

A liter is officially defined as exactly one cubic decimeter (1 dm³).

This means a liter is the volume of a perfect cube with sides that are each 10 centimeters long (10 cm × 10 cm × 10 cm).

Liter vs. Litre: Which Spelling Is Correct?

The difference between "liter" and "litre" is simply a regional spelling choice—the volume they represent is precisely the same!

Both spellings are correct, and the one you use depends on where you are.

• Liter: This is the international standard spelling, used in the United Kingdom, Canada, Australia, and most other English-speaking countries.
• Liter: This is the preferred spelling in American English.
