How Many Milliliters (ml) Are in One Quart (qt)?

Have you ever been in the middle of a recipe and realized you need to convert quarts to milliliters? Or maybe you're trying to figure out how much liquid a container holds. Whatever the reason, knowing how many milliliters are in a quart can be a handy conversion to have in your back pocket.

The answer is: There are 946.353 milliliters (ml) in one quart (qt).

This conversion can be confusing because the "quart" measurement is used in both the US customary system and the imperial system, and they are not the same!

The Difference Between US Quarts and Imperial Quarts

US Liquid Quart (US qt): This is the most common type of quart used in the United States. It is defined as 57.75 cubic inches.
Imperial Quart (Imp qt): This is the type of quart used in the UK and other Commonwealth countries. It is defined as 1.1365225 liters, or 69.35486 cubic inches.

As you can see, there's a significant difference between the two! So, when you're converting quarts to milliliters, it's crucial to know which type of quart you're working with.

Why Are There Two Types of Quarts?

The existence of two different quart measurements stems from historical differences in measurement systems. The US system is based on the English system, but it has evolved over time to include its own unique set of units.

How to Remember the Conversion:

"946" is a good number to remember! It's the approximate number of milliliters in one US liquid quart.
Think "almost a liter": A liter is roughly 1000 milliliters, and a quart is a little less than that.

Practical Examples:

Cooking: A recipe calls for 2 quarts of chicken broth. You know that 1 quart is approximately 946 ml, so you'll need about 1892 ml of chicken broth.
Gardening: You need to mix a solution of 1/4 quart of liquid fertilizer with water. That translates to about 236.5 ml of fertilizer.
DIY projects: You're trying to figure out how much paint to buy for a project. If the container is 1 quart, you'll know it holds about 946 ml of paint.

Conclusion:

Knowing how to convert quarts to milliliters can be extremely useful in everyday life. Now that you understand the difference between US and imperial quarts and have a handy conversion number to remember, you'll be able to easily handle any liquid measurement situation!
