Liters, gallons, ml, cups.
Converts between liters, gallons (US), fluid ounces, milliliters, cups, and cubic units.
1 US gallon = 3.7854 L. Note UK gallons (Imperial) are larger at 4.546 L.
This US-vs-UK gallon difference is a frequent source of confusion for fuel efficiency comparisons — a car rated in 'miles per gallon' means something different depending on which gallon is being used, roughly a 20% swing.
1 liter ≈ 0.2642 US gallons.
US gallon = 3.785 L; UK gallon = 4.546 L. Watch for this in recipes and fuel efficiency.
Yes — US cup = 240 ml, metric cup = 250 ml, UK cup = 284 ml. Recipes usually specify one.
Because cup measurements vary by country, following a US recipe with a metric cup (or vice versa) can throw off ratios enough to matter, especially in precise baking — weighing ingredients in grams avoids the issue entirely.
