$gallons = \frac{milliliters}{3785.41}$

How to Convert Milliliters to Gallons

1 ml $= 0.0002641721$ gallon
1 gallon $= 3785.411784$ ml

The steps to convert milliliters to gallons (US liquid gallons) are given below: 

Step 1: Note down the volume in mL.

Step 2: Multiply the given number by 0.000264. 

(or divide the given number by 3785.41.)

Example: How many gallons are in 2 ml?

2 ml $0.000264 = 0.000528$ gal 

So, there are 0.000528 US gallons in 2 milliliters.


Number of gallons $= \frac{2}{3785.41} = \frac{200}{378541} =  0.000528$ gal


A milliliter (symbol: ml or mL) is a unit of volume. It is not an S.I. unit but accepted in the S.I. system.

To measure larger quantities of liquid, we use liters. To measure smaller quantities of liquid, we use milliliters. Milliliter is used to measure a small amount of liquid like medicine bottles and perfume bottles. Various measurement devices like pipettes or beakers use milliliters as the unit of measurement.    


Gallon (symbol: gal) is a customary unit used to measure volume or liquid capacity. In the United States (US), gallons are often used for larger containers, such as half gallon tubs of ice cream or one-gallon cartons of milk. 

Example of container with capacity of 1 gallon

The gallon is a unit of volume which usually refers to the United States liquid gallon. There are three definitions in current use:

In this article, we learned about the units of volume—gallons and milliliters—and how to convert milliliters to US liquid gallons, steps, formulas. Let’s solve a few examples to understand this better.

Solved Example on Milliliters to Gallons Conversion

1. Convert 3,78,541 milliliters to gallons.


1 gallon = 3,785.41 milliliters.

We can convert given millimeters to gallons by dividing the quantity by 3,785.41.

 So, quantity in gallons $= \frac{378541}{3785.41}$

                                         $=  \frac{37854100}{378541}$

                                        $= 100$ gallons


you can multiply 3,78,541 milliliters by  0.000264 to get the number of gallons.

Gallons $= 3,78,541\times0.000264 =  99.934824 = 100$ approx.

2.  Convert 5 gallons (US) to milliliters.


1 US Gallon $= 3785.41$ milliliters

5 US gallons $= 5\times3785.41 = 18,927.05$ ml

Therefore, 5 Gallons is equal to 18,927.05 ml

3. The capacity of a bottle is 9877 milliliters. Find the capacity in gallons (US).


Gallons $= 9877\times0.000264 = 2.61$ gallons (approx.)


Gallons $= \frac{9877}{3785.41} = \frac{987700}{378541} = 2.61$ gallons (approx.)

4. Jenny bought two gallons of milk. She wants to pour this milk into 600 ml bottles. How many bottles will be required? 


Convert 2 gallons to milliliters.

1 gallon $= 3785.41$ ml 

So, 2 gallons $= 2 \times 3785.41$ ml $= 7,570.82$ ml

Number of 600 ml bottles required to fill 7570.82 ml $= \frac{7570.82}{600} = 12.6180$

So, the number of bottles required is 13.

5. Convert 5 milliliters to gallons.


1 gallon $= 3,785.41$ milliliters

$? = 5$ ml

Divide the number of milliliters by 3785.41 to find the equivalent gallons.
