Ever find yourself halfway through a recipe when you come to a conversion you’re not ready for? It happens to me all the time.

So, to save myself the headache of guessing (or guessing wrong!) I came up with a handful of cooking resources to help me understand different units of measurement. This time, we’re tackling quarts, gallons, and everything in between.

What is a gallon?

A gallon is a unit of volume often used to measure large volumes of liquids in the US customary system of measurement. It’s usually abbreviated ‘gal’ and equals 128 US fluid ounces, 3.79 liters, or 4 quarts.

What is a quart?

A quart is a unit of liquid capacity or volume used in the Imperial system of measurements. Typically abbreviated as ‘qt,’ it equals one-fourth or a quarter of a gallon, 2 pints, or 4 cups.

Quarts to gallons conversion table

When cooking or baking, the ingredients are listed in certain units of volume. If you’re dealing with quarts or gallons and don’t have the proper measuring cups, this conversion chart will help!

The basic metric is that there are 4 US quarts in ONE US gallon.

Unit	Equivalent
1 gallon	4 quarts
½ gallon	2 quarts
1 quart	¼ gallons
8 quarts	2 gallons

There is a conversion formula that you can use to convert quarts to gallons and vice versa:

Gallons = Number of quarts x 0.25

Note that 0.25 is the conversion factor and is constant for every conversion.

Here is how you can alter the above formula for calculating quarts:

Quarts = Number of gallons / 0.25

Liquid measurements vs dry measurements

When measuring ingredients, the liquid volume versus dry volume will vary significantly, so using the same measuring cups for both won’t always work. That’s why it’s best to use liquid measuring cups for fluids and dry measuring cups for dry measuring.
