Overview
About the Litres to Gallons Converter
Turn Litre into Gallon (US) with an exact factor. Type a value and get gal, every other volume unit, and the working — all locally, with nothing uploaded.
Litre and Gallon (US) describe the same quantity on two different scales, and converting between them is a single arithmetic step once you know the exact factor. This page does that step in your browser: type a value in L and the gal result appears immediately, alongside the same figure in every other volume unit.
The conversion
One L is exactly 0.264172 gal:
gal = L × 0.264172
L = gal × 3.7854Multiply to go one way, divide (or multiply by the inverse) to come back. The factor is a defined constant, not a measurement, so it never needs rounding.
Worked example
10 L = 2.6417 gal. Enter 10 in the box above and you will see exactly that, plus the value carried across the rest of the volume scale so you can sanity-check it against a unit you already recognise.
About these units
Volume conversions have a wrinkle worth remembering: the US and UK gallons differ by about 20%. The figures here use the US customary definitions for cups, tablespoons, pints and gallons, and label the UK gallon separately.
Converting the other way
Press Swap to turn this into a gal-to-L converter in place. The inverse factor, 1 gal = 3.7854 L, is shown in the arithmetic panel so you can check the reverse calculation independently.
Step by step
How to use the Litres to Gallons Converter
Enter the value in L (litre) that you want to convert.
Read the answer in gal, which updates the moment you type.
Scan the full volume table to see the same value in every other unit at once.
Copy the result, or press Swap to convert back the other way without re-entering anything.
Why use it
Benefits and common use cases
What this tool is good for, and what it deliberately does not try to do.
Exact, defined factors
Every volume conversion here uses the internationally defined relationship between L and gal, so the answer is as precise as the standard that fixes it rather than an approximation.
The whole category at once
Alongside the gal answer you get the same value expressed in every volume unit, so you can find the one you actually need without converting twice.
Private by construction
The arithmetic runs in your browser's own JavaScript. The numbers you enter are never sent to a server — close the tab and they are gone.
Questions
Frequently asked questions
Short, honest answers about quality, limits and privacy.
How many gallon (us) are in one litre?
One L equals 0.264172 gal. Multiply any L value by 0.264172 to get gal — for example, 10 L = 2.6417 gal.
What is the formula to convert L to gal?
gal = L × 0.264172. The page does this multiplication for you and also lists the inverse, 1 gal = 3.7854 L.
Is this volume converter accurate?
Yes. It uses the exact defined factor for L and gal and full double-precision arithmetic. The only rounding is in how many decimals are shown, which you control with the precision menu.
Are my numbers uploaded to a server?
No. The conversion runs entirely in your browser, so nothing you type leaves your device. There is no account, no logging and no network request of any kind.
