About this converter
Litres and gallons appear on fuel receipts, tank sizes, recipes and packaging. The catch is that the word “gallon” means different volumes depending on where you are. This tool supports both **UK (Imperial)** and **US (Customary)** definitions so you always get the right match for your context.
The relationships are exact: 1 UK gallon = 4.54609 litres and 1 US gallon = 3.785411784 litres. To convert litres to gallons, divide by the litres-per-gallon for your chosen system. To convert gallons to litres, multiply by that figure. Switch system to compare UK and US results for the same input without retyping your number.
Presets cover typical tank sizes and kitchen measures, which makes quick checks painless. The result updates as you type and stays in a clean block ready to copy. Because the factors are defined by standards, answers will match reputable references and remove guesswork when reading manuals or comparing products sold in different markets.
Use this page for fuel planning, brewing and recipes, aquarium sizing, water butts, or any task that hops between metric and imperial. Keep it bookmarked if you work with stock lists or shipping where both systems appear in the same conversation. Clear inputs, accurate results and no faff.
