When talking about liquid ingredients and everyday drinks like soda, milk and others, the most common units of measurement that we use are liters and gallons especially if they come in large volumes.

So maybe you can start asking yourself, if I can chug a gallon of milk in a day, how many liters would that make? It is also very important to know how many liters in a gallon, especially for conversion purposes in cooking. On that note, how many liters are in a gallon?

**What is Liter?**

Liter is a unit used in measuring liquid volume capacity and is expressed using the abbreviation *L. *To help us visualize a liter, we need to remember that a liter would be equivalent to 1000mL or 4 cups, according to Gallons to Liters . A liter is also equivalent to 3 soda cans or two pints of beer.

1 liter = 1000 mL = 4 cups

1 liter = 3 soda cans = 2 pints of bear

## What is gallon?

In the dictionary, a gallon is often defined as a large volume of something. It is considered as the largest unit of measurement for volume capacity. It is standardly expressed using the abbreviation gal. It is used in mainly in measuring liquid ingredients such as milk and others.

Like other units of measurement, there are also three types of gallons: the US gallon, the UK gallon and the imperial gallon. There are two important things to consider here. First, the imperial gallon is used as the basis for old British recipes. Second, the imperial gallon is just the same with the US gallon. The reason for this will be discussed in the next sections.

## What is US gallon?

Like the cup, gallon is also used as a unit of measurement for volume of both dry and liquid ingredients. Like all other unit conversions too, the gallon is measured in UK, imperial and US conversions. The US gallon when converted to liters would be 3.79.

According to Unit Converters, after the British colonial rule in the US, the US gallon was used particularly in measuring wine but evolved later on as a unit measurement for dry ingredients too like grains and corn, among others.

At present, the US gallon is an important unit of measurement in US supermarkets because it is used as the standard measurement for large containers of liquid products such as milk and even gasoline.

**How many Canadian gallons are in a US gallon?**

It was not only after the 1970s that Canada shifted to the US metric system. At that time, one gallon in Canada would be composed of around 5 liters. But upon shifting to the US metric system, one Canadian gallon would have 4 liters in it. But the question here is how many gallons are in a US gallon. The answer, according to Aqua Calc, is 0.86 gallon.

1 US gallon = 0.86 Canadian gallons

**How many liters in a gallon?**

In here, we will be looking at the strict conversions of liters to gallons. In industrial settings or for commercial purposes, gallons to liters are converted in the US as 4 and in the UK 5. But using strict conversion values, one US gallon would be composed of 3.79 while the UK gallon would have 4.55 liters in it.

1 gallon (US) = 3.79 liters = 4 liters (US)

1 gallon (UK) = 4.55 liters = 5 liters (UK)

**How to convert from gallons to liters?**

So now that we have already mentioned the strict conversion values for gallons and liters, how do we convert them? For this, all you have to remember would be the conversion values for imperial/UK gallons to liters and the US gallons to liters and that would be 5.55 and 3.79, respectively.

For reference, here is a simple conversion table that you may follow if you ever find yourself caught up in gallon to liter conversion in the future.

**Conclusion**

In conclusion, gallons to liters come in handy because we use them in a lot of everyday activities like grocery shopping for big volumes of milk, liquid condiments and other liquid stuff.

Since both are used to measure larger volumes of liquid substances, we need to know the conversion value for each because at times, the label is in gallon and it would be very hard for us to visualize things and how much they would actually look like if not expressed in liters.
