kg to Gallons Calculator

Welcome to our kilograms to gallons page! 👋

Have you ever tried to decipher Benjamin's Franklin metaphor: "A teaspoon of honey is worth more than a gallon of vinegar?"

Yes, we know, chances are you didn't land here to learn language arts, but here, we pack our handy calculators with a lot of wisdom. 💡

If you're not familiar with the Imperial System, let us first introduce you to the two main different measuring systems:

  • The metric system that was introduced during the French Revolution and is based on the decimal system. It uses units like meters, kilograms, and liters and is now the standard system of measurement in almost every country in the world except for the United States, Liberia, and Myanmar.
  • The imperial system that dates back to the Middle Ages and uses units of measurement like inches, feet, pounds, and gallons. While it has been largely replaced by the metric system in most countries, it is still used in the United States and a few other places around the world.

What Are Gallons?

The US gallon is approximately 3.785 liters.

The UK gallon is about 4.546 liters.

When our kg-to-gal Calculator Might Be Useful:

  • Industrial workers: Many industrial processes require precise measurements of liquids, and knowing the volume of a liquid in gallons can be incredibly helpful for calculating things like storage space and transportation needs.
  • Farmers and agricultural workers: Measuring the volume of liquid fertilizers or pesticides in gallons can be critical for proper application and yield optimization.
  • Homebrewers: Converting the weight of ingredients like grains or hops to their corresponding volume in gallons is essential for brewing beer and other fermented beverages.
  • DIY enthusiasts: Whether you're mixing your own paint or making your own cleaning products, knowing the volume of liquids in gallons can help ensure accurate measurements and consistent results.

From Kilograms to Gallons in a Snap: How to Use Our Online Converter

Ready to convert your liquids from kilograms to gallons (or vice versa)? Our online calculator makes it super easy! Here's how to use it:

Step 1: Choose Your Liquid

First things first - select your liquid from our list of preset options. Whether you're working with milk, water, or oil, we've got you covered with pre-set densities to make your conversion as seamless as possible. And if you're working with a different liquid, no problem! Just enter the density yourself, and you're good to go. Below is a helpful list with densities for some commonly converted substances but please bear in mind that they are approximate values since the density of a substance varies depending on temperature and other factors.


Substance Density (kg/m³) Density (kg/L) Density (lb/cu in) Density (lb/cu ft)
Gasoline 740 0.74 0.026 46.19
Paint 1200 1.2 0.043 74.91
Beer 1027 1.027 0.037 64.11
Wine 981 0.981 0.035 61.24
Water 1000 1 0.036 62.43
Ethanol 789 0.789 0.028 49.26
Acetone 784 0.784 0.028 48.94
Diesel 835 0.835 0.301 52.13
Olive Oil 918 0.918 0.033 57.31
Hydrochloric Acid 1100 1.1 0.04 68.67

Step 2: Enter Your Kilograms

Next, enter the weight of your liquid in kilograms. Our calculator instantly does the math and displays the corresponding volume in gallons - no extra clicks necessary!

Step 3: Optional - Lock Your Fields

If you're doing multiple calculations and want to prevent accidental changes to certain fields, simply lock them in place. This feature is especially helpful if you're working with a specific density or volume and don't want to accidentally overwrite it.

Step 4: Optional - Try the Opposite Calculation

Need to convert gallons to kilograms instead? No problem! Simply enter the volume of your liquid in gallons, and our calculator will instantly show you the corresponding weight in kilograms.

Step 5: Optional - Reset and Start Over

If you're finished with your current conversion and want to start fresh, simply hit the reset button, and our calculator will clear all fields so you can start over.

And that's it! With our online converter, you'll be able to convert kilograms to gallons (and back again) in a snap.

Converting Kilograms to Gallons: The Formula

Gallons = Kilograms / Density (in kg/L) * Conversion Factor

For example, if you have 20 kilograms of milk with a density of 1.03 kg/L and you want to convert it to gallons, you would use the following formula:

Gallons = 20 / 1.03 * 0.264172 = 5.13 US gallons

Keep in mind that there are different types of gallons based on the country or region you're in. In the United States, a gallon is equal to 3.78541 liters, while in the UK, a gallon is equal to 4.54609 liters. This means that the conversion factor will be different depending on the type of gallon you're working with.

To make things easier, here's a list of the conversion factors for different types of gallons:
