1 US Liquid Gallon = 4 US Liquid Quarts
When you are trying to measure liquids, there is no question that two of the most common units of measurement that you need to use are quarts and gallons. However, more times than ever, when you are trying to convert gallons to quarts or the other way around, we see people struggling. So, whenever you need to convert gallons to quarts, you need to do a quick search on Google.
While this may seem to be practicable especially when you don’t need to make a lot of conversions, when you are at school or you need these conversions for your work, this simple step will cut your productivity. So, it is time to stop doing this and finally learn how many quarts in a gallon.
We believe that the best way that you never need Google again to make your conversions from gallons to quarts is to learn and understand how you can do it on your own. Besides, before that, it is important that you know a bit more about each one of these units of measurement as well as about the relation between them. So, let’s get started.
Discover how many quarts there are in a cup.
What Is A Gallon?
One of the things that you need to understand is that the gallon is a unit of measurement of both the United States Customary System and the Imperial or British Measurement system. Besides, you need to keep in mind that the gallon is a unit of volume and this is why it is mainly used to measure liquid substances or ingredients.
While the gallon is part of both measuring systems, you should keep in mind that the United States liquid gallon (that we are looking at today) is different from the United States dry gallon and from the British or Imperial gallon. So that you know:
1 US fluid gallon = 4 US fluid quarts
1 US dry gallon = 4 US dry quarts
1 Imperial gallon = 4 Imperial quarts
The United States gallon is equal to 128 United States fluid ounces as well as it is equal to 3.785 liters. Besides, you should also keep in mind that 1 US liquid gallon is equal to four cups, eight pints, or sixteen cups.
The gallon tends to be also referred to as gal.

What Is A Quart?
A quart, just like the gallon, is a unit of measurement of both the United States Customary System and the Imperial or British Measurement System. Besides, it is worth pointing out that the quart is a unit of volume.
Even though the quart belongs to both measuring systems, just like the gallon, the quart is different. So, it’s important that you keep in mind that the United States liquid quart (the one that we are studying today) is different from the United States dry quart as well as it is also different from the Imperial or British quart.
While the United States liquid quart is equal to 32 United States fluid ounces, to one-fourth of a gallon, and to 2 pints, the Imperial quart is 20% larger. Besides, we can also state that the United States liquid quart is equivalent to four cups.
One of the easiest ways to see the difference between the three quarts measurements is by looking at them in terms of liquid ounces and milliliters:
1 United States Liquid Quart = 32 US liquid ounces = 946.353 milliliters
1 United States Dry Quart = 37.24 US liquid ounces = 1101.32 milliliters
1 Imperial Quart = 40 Imperial liquid ounces =1136.52 milliliters
The quart tends to be often referred to as qt.
Quarts And Gallons Around The World
As we already mentioned above, both quart and gallons ate divided into three types:
- the United States gallon and quart
- the United Kingdom gallon and quart
- the Imperial gallon and quart.
For example, the United States gallon is made up of four quarts while the Imperial gallon is made up of more than five quarts.
On the other hand, one Imperial quart is equal to 40 liquid ounces while the United States quart is equal to 32 fluid ounces. If we only revolve around these three types, the message is clear: the United Kingdom and Imperial units are 20% bigger in conversion than their United States counterparts.
This is important because it also tells you about how quarts and gallons are understood in terms of conversion in many parts of the world.
For example, Canada and countries in the Pacific such as Australia and New Zealand have already adopted the United States gallon to quart conversion while the United Kingdom and its Commonwealth countries have adopted the United Kingdom and/or Imperial measurements depending on the use. For cooking, they usually use the Imperial gallon and quart and in other things, they use the United Kingdom gallon or quart.

Why Is The United States Gallon Different To The United Kingdom Gallon?
This section needs a little bit of history.
The United States gallon is actually a vestige of the obsolete British Imperial system of measurement which was introduced in the Americas when the British colonial rule was in power. This one measures equates one gallon to 3.78 liters or 128 fluid ounces.
Learn more about the United States Customary units.
The United States gallon came into existence when Queen Ann of the British monarchy decided that all liquid ingredients shall all be slumped under one metric system.
In the year 1824, the United Kingdom turned their back from the Imperial gallon (which has the same measurement as the United States gallon) and devised the United Kingdom measurement. In this, all measurements for volume, regardless of divisions between dry and liquid ingredients measures gallons as equivalent to 160 fluid ounces or 4.5565 liters.
