Liquid Measurement - Number of Quarts in a Gallon?

Useful Information for Cooking

Quarts and gallons are units of liquid measure that are currently used mainly in the United States.

One gallon consists of four (4) quarts. However, we can break this down further to include teaspoons, tablespoons, cups (measuring cups for cooking, not coffee mugs), pints, quarts and gallons. We can also include ounces which are another unit of liquid measure.

It should be noted that in this hub I am discussing liquid measure.

NOTE: Ounces and pints are also units of solid measure but the weight and volume are not necessarily the same for liquid and solid measures.

Since the logical uses of this knowledge of liquid measure are cooking and comparing units in a grocery store, I will put these measures and their relationships in a table format starting with the smallest unit, which is a teaspoon, and continuing to the largest, which is a gallon:

3 Teaspoons = 1 Tablespoon = ½ Fluid Ounce

16 Tablespoons = 1 Cup = 8 Fluid Ounces

2 Cups = 1 Pint = 16 Fluid Ounces

2 Pints = 1 Quart = 32 Fluid Ounces

4 Quarts = 1 Gallon = 128 Fluid Ounces

This is a really good subject. Its funny how many people don't know things like this,(I didn't!,)so it is always good to have somewhere you can go to learn, quick.

Keep up the good work!

Nice stuff!

Mike, I did state in the second paragraph that this article was dealing with liquid rather than dry measure and that there was a difference even though the names were the same.

However, I have now bolded that statement and made it a separate paragraph as well as adding the word "fluid" in front of each use of "ounce"

Thanks for the FYI on this.


Mike on September 20, 2009:

Just a FYI. You should specify fluid ounces. My wife doesn't understand the difference between a fluid oz and an ounce. One time the vet suggested a diet for our dog in ounces of food per day. My wife was using half of a 20 oz pop can to measure 10 ounces. doh!
