what it does
The liters-to-gallons trick is one number: multiply by 0.264172 and the gallons appear. It's the conversion every driver, brewer and aquarium owner meets the moment a liter shows up where gallons live.
It shows up wherever liters cross into gallons territory: a European fuel pump counting up in liters while the American brain wants gallons (40 liters is about 10.6, and the tank sighs), a big water jug that holds 18.9 liters but is sold as five gallons, or an aquarium measured in liters that someone keeps asking about in gallons.
The rough version is the friendliest conversion around: 4 liters is about a gallon. Four coffee carafes, one jug, done. For anything that involves a receipt or a fish tank, the widget below is exact and doesn't spill.
Type any liter number and the widget answers in gallons instantly, with the math written in the hint. Click the result to copy it, and hit swap when the argument flips — the gallons-to-liters version is one click away.
