Unleash the Power of Conversion: Master Liters to Gallons (l to gal) with Formula, Definition, and Facts.
When we want to measure liquid volume, two of the most commonly used units are gallons and liters. The liter is the primary unit of volume in the metric system, which is also a widely accepted unit in the International System of Units. In contrast, the gallon is a unit of volume that is commonly used in the United States as a customary unit. While most countries in the world follow the metric system, the US uses customary units like pints, quarts, and of course, gallons.
The metric unit of volume primarily used for measuring liquids is called a liter and is abbreviated as "L" or "l." For smaller quantities of liquid, we measure in milliliters, abbreviated "mL." It is worth noting that one liter is equal to 1000 milliliters.
A gallon, on the other hand, is a unit of measurement for liquids equal to eight pints or 3.785 liters. Unlike the metric system, the gallon is a US customary unit of volume, also used in the imperial system of measurement. However, it is essential to remember that the American gallon is smaller than its British counterpart and has a different conversion factor. The abbreviation for gallon is "gal" or "US gal."
For easy conversion between liters and gallons, we can use a conversion calculator, like the one at here. The process is simple: enter the measurement in liters you want to convert in the "From" box, and the equivalent measurement in US gallons will appear in the "To" box automatically.


To convert liters to gallons manually, use the following formula: Gallons = Liters x 0.264172. This formula tells us that there are approximately 0.264 gallons in one liter. Conversely, to convert gallons to liters, multiply the number of gallons by 3.785.
To illustrate with an example, suppose you want to convert ten liters to gallons. Simply multiply the amount you have (10 liters) by the conversion factor (0.264 gallons per liter), which equals 2.64 gallons. Therefore, ten liters are equivalent to 2.64 gallons.
In summary, while gallons and liters are both used to measure liquid volume, the former is a customary unit primarily used in the United States, while the latter is the primary unit of volume in the metric system. Conversion between the two units is simple, and you can use either a conversion calculator or a simple formula to obtain the equivalent measurement.

When dealing with volumes and capacity measurements, liters are the go-to unit in the metric system. Symbolized as "l," liters can also be abbreviated as "L" or "$\ell$." It is worth mentioning that one-liter is equivalent to one cubic decimeter, and it has been internationally recognized as part of the SI unit since 1964.
On the other hand, gallons are a customary unit of measurement used mainly in the United States, the United Kingdom, and their territories. While gallons can be abbreviated as "gal," liters represent the most prevalent international unit in measuring volumes and capacities.
If you ever need to convert between liters and gallons, you can use the formula: Gallons = Liters $\times$ 0.264172. It means that one US gallon equals approximately 3.785 liters, and one liter is equal to 0.219969 imperial gallons.
It is worth mentioning that the weight of a gallon depends on the substance being measured. For example, a gallon of milk weighs more than a gallon of water because of the fat content.
Let's take a look at some examples to grasp the process better:
1. Say you have a container large enough to hold 20 liters of petrol. What is its volume in gallons?
Solution:
Using the above formula, we have:
- Gallons = 0.264172 $\times$ liters
- 20 liters = (0.264172 $\times$ 20) gallons
- = 5.28344 gallons
Therefore, the volume of the container is 5.28344 gallons.
2. If you want to convert 3 liters to gallons, what would be the value?
Solution:
Using the above formula, we have:
- Gallons = 0.264172 $\times$ liters
- 3 liters = 0.792516 gallons
Therefore, 3 liters = 0.792516 gallons.
3. If a barrel can hold 60 US gallons of water, how many liters of water can it hold?
Solution:
One liter is equivalent to 0.264172 US gallons. Thus, 60 US gallons = (60 $\times$ 3.785) liters = 227.1 liters.
Hence, a barrel can hold 227.1 liters of water.
4. If a diesel tanker can hold 6000 liters of diesel, what is the equivalent in gallons?
Solution:
Using the above formula, we have:
- Gallons = 0.264172 $\times$ liters
- 6000 liters = 1585.032 gallons
Therefore, a diesel tanker can hold 1585.032 gallons of diesel.
5. If Jane uses 3 liters of water for cooking and 1000 liters for other purposes, what is the total usage of water in gallons?
Solution:
Using the above formula, we have:
- Gallons = 0.264172 $\times$ liters
- Total usage of water = 1003 liters = 265.228 gallons
Therefore, the total usage of water is 265.228 gallons.

The quantity of water usage is 264.96 gallons, which can be calculated by multiplying 0.264172 by 1003 gallons. To test your knowledge and skills, take this quiz.
To convert liters to gallons, multiply the value in liters by 0.264172. In the United States, one gallon is equivalent to 3.785 liters, while the abbreviation for gallons is "gal." Both containers, the US and Imperial gallon, have the same capacity, but the Imperial gallon is about 20% larger than the US gallon.
Four liters are slightly more than a gallon, equivalent to 1.06 gallons, to be exact. Contrarily, one gallon is bigger than three liters in terms of measurement.
In modern times, two types of gallons are commonly used: the United States and United Kingdom gallons. The US has liquid and dry gallons, while the UK's only gallon unit is known as the Imperial or British gallon. All three types are utilized for measuring various substances such as fuel, oil, paint, and milk.
