How Many Liters Are in a Gallon?

Converting measurements is a vital skill to have in a kitchen. Whether you’re cooking with cannabis at home or in a commercial setting, you might need to make fewer or more servings than a recipe calls for.

Liters and gallons are common liquid measurements used in cooking. Knowing how to convert between the two can help you create delicious edibles at scale.

Converting liters to gallons is easier than you think. You don’t need to be a math whiz to determine the liter or gallon equivalents of a liquid’s volume.  

Here, we cover the differences between imperial and metric systems and provide simple formulas to convert liters to gallons or vice versa. Let’s find out how many liters are in a gallon.

TL;DR (Too Long; Didn’t Read): There are 3.785411784 liters in a gallon.

What Is Liquid Volume?

Cannabis cooking often involves measuring different dry and wet ingredients. Liquid ingredients include syrups, honey, water, oils, stock, wine, milk, fruit juices, and more. Measuring spoons and cups help you use the correct amounts of each ingredient in the recipe.

How does volume come into play in cooking edibles?

All objects take up space, which is measured in volume. Volume, also known as an object’s capacity, refers to the amount of space an object or substance occupies or that is enclosed within a container.

Liquid volume refers to the amount of liquid within a container. Volume is used in nearly all recipes, whether it’s the amount of oil used to make infused brownies or the chicken broth used to make a hearty and intoxicating soup.

Liquid volume can be measured with metric units, including milliliters (ml), centiliters (cl), liters (l), and kiloliters (kl). Liquids can also be measured with US customary and U.K. imperial units that use fluid ounces (fl oz), cups (c), pints (pt), quarts (qt), and liquid gallons (gal).

Knowing how to convert liquid volume measurements is critical in any kitchen and bakery. Let’s find out more about the different systems of measurement used worldwide.

What Are Metric, US Customary, and Imperial Systems of Measurement?

Most countries use the international system of units, also known as the metric system. However, the United States uses its own US customary system of measurements, based on the British imperial system.

Although the US and imperial system use the same units of measurement (fl oz, c, pt, qt, and gal), the number of ounces in each unit is larger in the imperial system. For example, one imperial gallon equals 160 fl oz, while a US gallon equals 128 fl oz.

Many liquid ingredients include the US customary units and their metric conversions to milliliters. For example, a 16 fl oz bottle of olive oil is equivalent to 473 ml, 0.473 liters, or 0.124953 gallons.

If you’re working on a recipe that requires you to convert liters to gallons, you’d be converting a metric unit into a US customary unit of volume.

What Is a Liter?

A liter is a unit of volume in the international standard or metric system of measurement. It’s used to measure various liquid volumes but can also measure non-liquid volumes, including backpacks, car trunks, and refrigerators, as well as fuel (outside of the US). 

According to Merriam Webster, a liter is a “metric unit of capacity equal to one cubic decimeter.”

In a cubic decimeter (equal to one liter), there are 1,000 cubic centimeters (cc). In the US, cubic centimeters are generally used in the automotive and medical fields.

From 1901-1964, liters were defined as the volume in 1 kilogram of water at standard pressure and peak density. However, due to various factors that can affect the mass-volume relationship of water, the definition was changed back to the previous and current definition.

What Is a Gallon?

Gallon units of measurement are used to measure liquid capacity in US customary and imperial systems of measurement. US gallons are 3.785 liters, while imperial gallons are 4.54609 liters. 

According to Merriam Webster, a gallon is “a unit of liquid capacity equal to 231 cubic inches or four quarts.”

Both systems divide gallons into four quarts. Four quarts are divided into two pints, and two pints are divided into two cups.

In the US, gallons are used to measure large containers, including cartons of milk and tubs of ice cream, as well as to express fuel volumes.

For many recipes, gallon units of measurement are too big. Nevertheless, it’s important to understand these units of measurement and know how to convert units.

What Is an Imperial Gallon?

An imperial gallon, also known as a UK gallon, is used in many countries, including the United Kingdom, Canada, Ireland, New Zealand, Australia, and some Caribbean countries. 

An imperial gallon equals four imperial quarts, 4.54609 liters, or 277.42 cubic inches. An imperial fluid ounce equals 1/160 of an imperial gallon.

Under the definition of an imperial gallon, there are 4.54609 liters when the water’s temperature is about 62º F or 17º C.

What Is a US Liquid Gallon?

The US customary system of measurements uses US liquid gallons as a unit of measurement. A US liquid gallon equals 3.7854 liters. At 10º C, a US gallon weighs 3.78 kilograms or 8.34 pounds. A US gallon is about 16.6 percent smaller than the imperial gallon.

What Is a US Dry Gallon?

A US dry gallon, also known as a grain or corn gallon, is based on an old British dry measure of volume that weighs 268.8025 cubic inches or 4.405 liters. The US fluid gallon is about 14.1% smaller than the dry gallon. The imperial gallon is about 3.2% larger than the dry gallon.

How Many Liters Are in a Gallon?

One of the most common questions on Google about liter conversions is, “how many liters are in a gallon?” When making cannabis edibles, this may come up if you’re working with liquid ingredients.

Generally, there are 3.785411784 liters in one gallon. However, this can vary depending on the type of gallon: US dry, US liquid, or imperial gallon. There are 4.54 liters in an imperial gallon and 4.405 liters in a US dry gallon.
