If you cook or bake with cannabis, you’ve probably had to convert volume measurements to get your desired edible servings and dose. Converting milliliters (ml) to gallons (gal) or vice versa is expected when making cannabis-infused edibles, tinctures, and topicals.
This volume conversion guide covers the difference between milliliters and gallons, shows you how to convert between the two, and answers frequently asked questions about milliliter conversions. Now, let’s find out how many milliliters are in a gallon.
TL;DR (Too Long; Didn’t Read): There are 3,785.411784 milliliters in one gallon.
What Is Liquid Volume?
When cooking with cannabis, you will use a broad range of wet and dry ingredients. Liquid ingredients such as milk, juice, oil, and water are commonly measured with measuring cups and spoons when following a recipe.
Liquid volume is the amount of space a liquid takes up in a container and can be measured with metric, US customary, and UK imperial units of measurement.
- Metric: Milliliter (ml), centiliter (cl), liter (l), and kiloliter (kl)
- US customary: Fluid ounce (fl), cup (c), pint (pt), quart (qt), and liquid gallon (gal)
- UK imperial: Fluid ounce (fl), cup (c), pint (pt), quart (qt), and liquid gallon (gal)
You may notice that US customary and UK imperial measurement systems use the same units of measurement. However, there is a difference in amount between US customary and UK imperial units of measurement. We will go more in-depth below.
Metric, US Customary, and UK Imperial Measurements
Did you know that the United States uses the customary measurement system based on the UK imperial system? In contrast, most of the world uses the International System of Units, also known as the metric system.
The US and UK systems use the same units of measurement (fl, c, pt, qt, gal), but there is a difference between the volume measurements. The number of gallons, quarts, fluid ounces, and pints is larger in the imperial system. For example, a US liquid gallon is 128 fluid ounces, while one imperial gallon equals 160 fluid ounces.
Some liquid products will include the US customary and metric values. For example, a 16-fluid-ounce bottle of cooking oil equals 473 milliliters, 0.124953 gallons, and 0.473 liters.
When cooking or baking with cannabis, you may need to convert milliliters to gallons. The conversion process requires converting a metric unit (milliliter) into a US customary unit (gallon) of volume. We’ll show you how to convert between the two below.
What Is a Milliliter?
A milliliter, abbreviated as ml, is a unit of volume in the metric system of measurement. A milliliter is “a unit of capacity equal to 1/1000 liter,” 1/1,000,000 cubic meters, or one cubic centimeter.
A milliliter’s base unit is the liter or spelled “litre” in the metric system. “Litre” was part of the French metric system and derived from “litron,” an old version of the French litre.
Today, milliliters are used to measure the amount of liquid in small containers, such as cans, medicine, perfume, toothpaste, and shampoo. Milliliters can be measured with measuring cups, graduated cylinders, pipettes, and beakers.
What Is a Gallon?
A gallon, abbreviated as gal, is a unit of liquid volume in the imperial and the US customary measurement systems. A US gallon is “a unit of liquid capacity equal to 231 cubic inches [3.785 liters] or 4 quarts.”
The imperial gallon is used in the United Kingdom, Canada, and certain Caribbean countries. It is defined as 4.54609 liters. Like a US gallon, an imperial gallon is a unit of fluid volume equal to four quarts. One quart is equal to two pints, and each pint is equivalent to two cups.
In the US, liquid gallons are used to measure large containers, such as milk, water, fuel, paint, storage containers, aquariums, and coolers. The imperial gallon is not used as often as the US liquid gallon. For example, most countries use litres to measure fuel.
How Many Milliliters Are in a Gallon?
If you’re cooking or baking cannabis, you will likely need to use milliliter and gallon units of volume. One US liquid gallon is equal to 3,785.411784 milliliters.
Milliliters = (Amount of gallons) x 3785.411784
How Many Gallons Are in a Milliliter?
One milliliter is equal to 0.00026417205 gallons.
Gallons = (Amount of milliliters) ÷ 3785.411784
How to Convert Milliliters to Gallons
Converting milliliters to liquid gallons is simple. There are 3,785.411784 milliliters in a gallon. To convert milliliters to gallons, divide the milliliter value by 3,785.411784 to determine the equivalent value in gallons.
Use this formula when converting milliliters to gallons:
Gallons = Milliliters ÷ 3,785.411784
Examples:
1 ÷ 3,785.411784 = 0.00026417205 gallons
5 ÷ 3,785.411784 = 0.00132086026 gallons
10 ÷ 3,785.411784 = 0.00264172052 gallons
20 ÷ 3,785.411784 = 0.00528344104 gallons
25 ÷ 3,785.411784 = 0.0066043013 gallons
How to Convert Gallons to Milliliters
If you’re trying to convert large amounts of liquid capacity to smaller amounts, you may need to convert gallons to milliliters. Since there are 3,785.411784 milliliters in a gallon, you can multiply the gallon value by this value to convert gallons into milliliters.
Use this formula when converting gallons to milliliters:
Milliliters: Gallons x 3,785.411784
Examples:
1 gallon x 3,785.411784 = 3,785.411784 gallons
2 gallons x 3,785.411784 = 7,570.823568 gallons
5 gallons x 3,785.411784 = 18,927.05892 gallons
10 gallons x 3,785.411784 = 37,854.11784 gallons
20 gallons x 3,785.411784 = 75,708.23568 gallons

Things That Are Measured in Milliliters
One milliliter is measured in a small instrument, such as a pipette or beaker. Milliliters are sometimes used in the US for several reasons:
- Liquid medicine
- Beverages
- Perfume
- Liquid makeup
- Toothpaste
If a liquid is measured in another unit of volume, you can convert that unit to milliliters using the correct ml-gallon conversion formula.
How to Measure Milliliters and Gallons
Measure gallons and milliliters using measuring cups, teaspoons, and tablespoons, and then use the appropriate conversion formula to determine the milliliter equivalent. You can also use a pipette made from food-grade materials for your cannabis cooking or baking.
