Liters to Gallons Online

Updated 2026-10-24

Convert liters to US gallons online for free. Enter a volume in liters and SnapTools shows the exact value in gallons instantly, in your browser. Nothing is uploaded.

Most of the world measures volume in liters, but US fuel tanks, recipes, and container sizes are usually quoted in gallons. This converter uses the exact US-gallon figure (not the larger UK gallon) so a metric spec converts correctly. For the full family of volume units (milliliters, cups, pints, the UK gallon), use the Volume Converter.

// how to use

  1. 1 Type or paste a volume in liters into the input.
  2. 2 SnapTools converts it to US gallons as you type.
  3. 3 Copy the result, or use the slider for a quick scrub across common tank/container sizes.

// faq

Has the liter always been defined the same way?
Not quite. France introduced the liter in 1795 as the volume of a cube 10 centimeters on each side (one cubic decimeter). From 1901 to 1964, it was redefined as the volume of one kilogram of pure water instead, which turned out to be about 0.0028% larger than a true cubic decimeter. In 1964, the definition reverted to the simple geometric one still used today.
Does this convert to the US gallon or the UK gallon?
The US gallon. If you need the UK (imperial) gallon instead (about 20% larger), the full Volume Converter offers it as a separate unit.
What's the exact conversion factor?
1 liter is exactly 0.2641720524 US gallons, the reciprocal of the exact 3.785411784 liters per US gallon.
Why would I convert liters to gallons?
If you're reading a metric fuel-tank size, a European recipe, or a container spec and need the US-gallon equivalent for comparison or shopping.
What about the other direction?
Use Gallons to Liters, or the full Volume Converter for milliliters, cups, pints, and more.
